Kasten K10 by Veeam #

The Kasten K10 by Veeam® data management platform has deep integrations with Rancher by SUSE and comes with an extensive ecosystem of support across Kubernetes distributions and cloud platforms. This gives enterprise operations teams the flexibility to choose the deployment environments that best meet their needs - on-premises, public cloud, and hybrid. Kasten K10 is policy-driven and extensible. It delivers enterprise features such as full-spectrum consistency, database integration, automatic application discovery, multi-cloud mobility, and a powerful Web-based user interface.

For this guide, you will need the following:

Kasten K10 can be installed in a variety of different environments. To ensure a smooth installation experience, you can use the primer tool to perform several pre-flight checks to make sure that the prerequisites are met. This tool runs in a pod in the cluster and does the following:

Run the following command to deploy the primer tool:

curl https://docs.kasten.io/tools/k10_primer.sh | bash

Note

This will create and clean up a ServiceAccount and ClusterRoleBinding to perform sanity checks on your Kubernetes cluster.

Kasten K10 can be easily deployed from the Rancher Apps Catalog.

Note

In the unlikely scenario that pods are stuck in any other state, see the support documentation to debug further.

Note

If you are running on GKE and want to access the dashboard without local kubectl access, see K10 Dashboard Directly From the Google Cloud Console.

Direct access to the Kasten K10 dashboard requires a properly configured authentication method to secure access. For more information, see Kubernetes authentication. The next two sections provide an overview of the steps you can follow to configure an authentication method.

Proceed by following the steps to configure either basic authentication or token authentication in the next sections.

--set auth.basicAuth.enabled=true \
--set auth.basicAuth.htpasswd='example:$apr1$qrAVXu.v$Q8YVc50vtiS8KPmiyrkld0'

--set auth.basicAuth.enabled=true \
--set auth.basicAuth.secretName=my-basic-auth-secret

5.3 Kasten K10 dashboard overview #

 

The Kasten K10 dashboard is divided into several different sections, described below.

Tip

A guided tour is available when the Kasten K10 dashboard is accessed for the first time or via the option on the Settings page.

The top of the Kasten K10 dashboard displays a list of applications currently mapped to namespaces, any policies that might exist in the system, and a summary of the cluster’s backup data footprint.

After filtering for applications that have stateful services (defined as containing a persistent volume), this screen further categorizes applications as:

• Unmanaged: There are no protection policies that cover this object.

• Non-compliant: A policy applies to this object, but the actions associated with the policy are failing (because of underlying storage slowness, configuration problems, etc.) or the actions have not been invoked yet.

• Compliant: These objects have policies, and the policy SLAs are being respected.

Tip

You can filter the view by clicking the Compliant, Non-Compliant, or Unmanaged buttons.

The Kasten K10 platform equates namespaces to applications for ease of use and consistency with Kubernetes best practices. This also allows use of role-based authentication controls (RBAC) and mirrors the most common application deployment patterns. As shown later, policies can be defined to operate on more than one namespace or only operate on a subset of an application residing in a single namespace.

If you already have installed applications, clicking the Applications card on the dashboard will provide you with details.

An application is made up of multiple Kubernetes resources and workloads, including deployments and stateful sets.

Kasten K10 policies are used to automate your data management workflows. Policies combine actions you want to take (such as making a snapshot), frequency or schedule for how often you want to perform the action, and selection criteria for the resources you want to manage.

On the Policies card, you notice that no default policies are created at install time. A policy can be either created from this page or from the application page shown earlier.

Kasten K10 can invoke protection operations, such as snapshots, within a cluster without requiring additional credentials. This may be sufficient if Kasten K10 is running in the major public clouds and actions are limited to a single cluster. It is not sufficient for most production situations, where performing real backups, enabling cross-cluster and cross-cloud application migration, and enabling disaster recovery are essential.

To enable these actions that span the lifetime of any one cluster, Kasten K10 needs to be configured with access to external object storage or external NFS file storage. This is accomplished with location profiles.

Access profile creation from the Settings icon in the top-right corner of the dashboard or via the CRD-based Profiles API. Location profiles are used to create backups from snapshots, move applications and their data across clusters and potentially across different clouds, and to subsequently import these backups into another cluster.

To create a location profile, click New Profile on the profiles page.

When exporting to or importing from an object storage location, you must pick an object storage provider, a region for the bucket if being used in a public cloud, and the bucket name. If a bucket with the given name does not exist, it will be created.

If you use an S3-compatible object storage system that is not hosted by one of the supported cloud providers, an S3 endpoint URL must be specified.

Note

When certain cloud providers (like AWS or Microsoft Azure) are selected, provider-specific options (such as IAM Roles) will appear for configuration.

When you click Validate and Save, the configuration profile is created and a profile similar to the following appears:

Protecting an application with Kasten K10 is usually accomplished by creating a policy.

In this section, you learn about snapshots and backups, scheduling, and selection in the context of application protection policies.

Kasten K10 defines an application as a collection of namespaced Kubernetes resources associated with

While you can always create a policy from scratch through the policies page, the easiest way to define policies for unprotected applications is to click the Applications card in the main dashboard. This will allow you to see all applications in your Kubernetes cluster.

To protect any unmanaged application, simply click Create a Policy to open the New Policy dialog.

7.1 Snapshots and backups #

 

All Kasten K10 policies center around the execution of actions. You start by selecting the snapshot action with an optional backup (called an export).

See Snapshots and Backups in the Kasten documentation for more details.

7.1.1 Snapshots #

 

Snapshots form the basis of persistent data capture in Kasten K10. They are typically used in the context of disk volumes (PVC/PVs) used by the application but can also apply to application-level data capture (such as with Kanister).

Note

Several public cloud providers (including AWS, Azure, and Google Cloud) actually store snapshots in object storage, and they are retained independent of the lifecycle of the primary volume. However, this is not true of all public clouds. An independent backup would provide essential safety. Check with your cloud provider’s documentation for more information.

Snapshots, in most storage systems, are very efficient and have a very low performance impact on the primary workload, require no downtime, support fast restore times, and enable incremental data capture.

Storage snapshots usually suffer from constraints, such as having relatively low limits on the maximum number of snapshots per volume or per storage array. Most importantly, snapshots are not always durable. A catastrophic storage system failure will destroy your snapshots along with your primary data. Further, in several storage systems, a snapshot’s lifecycle is tied to the source volume. So, if the volume is deleted, all related snapshots might automatically be garbage collected at the same time.

Tip

It is highly recommended that you create backups of your application snapshots to ensure durability.

7.1.2 Backups #

 

Backups overcome the limitations of application and volume snapshots by converting them to an infrastructure-independent format, deduplicating, compressing, and encrypting them before they are stored in an external object store or NFS volume.

To convert your snapshots into backups, activate Enable Backups via Snapshot Exports during policy creation.

7.2 Scheduling #

 

There are four components to Kasten K10 scheduling:

• Action frequency: how frequently the primary snapshot action should be performed

• Export frequency: how often snapshots should be exported to backups

• Retention schedule: how snapshots and backups are rotated and retained

• Timing: when the primary snapshot action should be performed

7.2.1 Action frequency #

 

Kasten K10 snapshots can be set to execute at an hourly, daily, weekly, monthly, or yearly frequency, or on demand. By default, hourly snapshots execute at the top of the hour, while weekly, monthly, and yearly snapshots execute at midnight UTC.

You can also specify the time at which scheduled actions execute and sub-frequencies that execute multiple actions per frequency. Sub-hourly actions can be useful when you are protecting mostly Kubernetes objects or small data sets. See Advanced Schedule Options in the Kasten documentation for more information.

Warning

Care should be taken not to stress the underlying storage infrastructure or running into storage API rate limits. Further, sub-frequencies do also interact with retention (described below). For example, retaining 24 hourly snapshots at 15-minute intervals would only retain 6 hours of snapshots.

7.2.2 Export frequency #

 

When Enable Backups via Snapshot Exports is enabled, snapshots are exported as backups. By default, every snapshot is exported, but you can limit this to a subset by selecting a daily, weekly, monthly, or yearly export frequency.

7.2.3 Retention schedule #

 

A powerful scheduling feature in Kasten K10 is the ability to use a https://en.wikipedia.org/wiki/Backup_rotation_scheme#Grandfather-father-son [GFS retention scheme] for cost savings and compliance. With this backup rotation scheme, hourly snapshots and backups are rotated each hour with one graduating to daily every day, daily snapshots and backups are rotated each day with one graduating to weekly, and so on. You can set the number of hourly, daily, weekly, monthly, and yearly copies that need to be retained, and Kasten K10 will take care of cleanup.

Note

It is not possible to set a retention schedule for on-demand policies.

The default backup retention schedule is the same as the snapshot retention schedule. You can make these independent schedules, if needed. This allows you to create policies where a limited number of snapshots are retained for fast recovery from accidental outages while a larger number of backups are stored for long-term recovery. This separate retention schedule is also valuable when a limited number of snapshots are supported on the volume, but a larger backup retention count is needed for compliance.

Snapshots and backups created by scheduled runs of a policy can be retained and omitted from the retention counts by adding a k10.kasten.io/doNotRetire: "true" label to the RunAction created for the policy run.

Note

The retention schedule for a policy does not apply to snapshots and backups produced by manual policy runs. And you will need to clean up any artifacts created by manual policy runs.

7.2.4 Timing #

 

By default, actions set to hourly execute at the top of the hour. Other action frequencies execute at midnight UTC.

Unhide Advanced Options to select how many times actions are executed within the frequency interval. For example, if the action frequency is daily, you can specify the hour of the day and the minutes after the hour when the action is to start.

You can also customize the retention schedule by selecting which snapshots and backups will graduate and be retained for longer periods.

Tip

You can toggle whether to display and enter times in local time or UTC, but all times are converted to UTC and do not change for daylight savings time.

7.3 Selection #

 

You can specify which applications are bound to a policy by name or label.

7.3.1 Application name #

 

The most straightforward way to apply a policy to an application in Kasten K10 is to use its name (derived from the name of the namespace). You can even select multiple application names for the same policy.

If you need a policy to span similar applications, use the asterisk ('*') wild card. For example, if you specify 'mysql-*', Kasten K10 will match all applications whose names start with 'mysql-'.

Note

For policies that need to span all applications, use the asterisk wild card by itself.

7.3.2 Application label #

 

You can also use labels to bind a policy to multiple applications. For example, you could protect all applications that use MongoDB or applications that have been annotated with, say, the 'gold' label. Matching occurs on labels applied to namespaces, deployments, and statefulsets. If multiple labels are selected, a union (logical OR) will be performed, matching all applications with at least one of the labels.

Label-based selection can be used to create forward-looking policies, as such policy would automatically apply to any future application with the matching label. For example, if you use a label of 'heritage: Tiller' (for Helm v2) or 'heritage: Helm' (for Helm v3), the selector will apply the policy to any new Helm-deployed applications because the label is applied to any Kubernetes workload created by the Helm package manager.

7.3.3 Other resources #

 

Kasten K10 can also protect cluster-scoped resources without targeting any applications. To specify this, select None.

For more information about protecting cluster-scoped resources, see Cluster-Scoped Resources.

7.3.4 Customization #

 

You can further customize what is and what is not covered under a Kasten K10 application protection policy with:

• namespace exclusions

• exceptions

• resource filtering

When you have created a policy and have navigated back to the main Kasten K10 dashboard, you see the selected applications quickly switch from unmanaged to non-compliant. That is, a policy covers the objects, but no action has been taken yet. The applications will switch to compliant as snapshots and backups are run and the application enters a protected state. You can also scroll down the page to see the activity, how long each snapshot took, and the generated artifacts.

Note

More detailed job information can be obtained by clicking the in-progress or completed jobs.

8.1 Manual policy runs #

 

You can manually run a policy by clicking the run once button on the desired policy. Any artifacts created by this action will not be eligible for automatic retirement and will need to be manually cleaned up.

8.2 Restoring existing applications #

 

Restore an application via the Applications page in the Kasten K10 dashboard. To restore an application, simply click the restore icon in the application’s card.

Note

While Kasten K10 uses the "export" term for backups, no import policy is needed to restore from a backup. Import policies are only needed when you want to restore the application into a different cluster.

Next, you select a restore point. These are distinguished in Kasten K10 as having been generated manually or automatically through a backup policy.

A restore point may include snapshots (native to the cluster) and backups (exported outside the cluster) with the same data. When both snapshots and backups are present, the Kasten K10 provides you with the option to select the instance you want to use to restore the application.

Selecting a restore point brings up a side-panel containing more details on the restore point for you to preview before you initiate an application restore.

When you click Restore, Kasten K10 automatically re-creates the entire application stack into the selected namespace. This not only includes data associated with the original application but also the versioned container images.

Note

Restored PersistentVolumes may not have the annotations specified in the original PersistentVolume.

After the restore completes, you can go back to your application and verify that the state was restored to what existed at the time the restore point was obtained.

8.3 Restoring deleted applications #

 

Restoring a deleted application follows nearly the same process, except that removed applications are not shown on the Applications page by default. To discover them, you simply need to filter and select Removed.

When the filter is in effect, you see applications that Kasten K10 had previously protected but which no longer exist. These can now be restored using the normal restore workflow.

The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.

This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".

Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text.

A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition.

The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

You may also lend copies, under the same conditions stated above, and you may publicly display copies.

If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles.

You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties—​for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements".

You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.

You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation.
