CloudCasa Self-Hosted with SUSE Virtualization #

Deploying SUSE Virtualization and CloudCasa Self-Hosted together provides:

Modern enterprises are turning to open-source, Kubernetes-based virtualization platforms such as SUSE Virtualization to break down infrastructure silos, lower licensing expenses, and unify the management of virtual machines (VMs) alongside cloud native containers. Maintaining a robust data protection strategy is crucial, even within isolated or air-gapped environments. CloudCasa Self-Hosted offers a cloud native backup and recovery solution designed to protect critical workloads, ensure operational continuity, and streamline disaster recovery.

Key objectives covered in this guide include:

CloudCasa Self-Hosted is cloud native and is deployed onto a Kubernetes cluster. In this architecture, the CloudCasa backup server is deployed onto a single-node SUSE Rancher Kubernetes Engine (RKE2) cluster, running on a SUSE Linux Enterprise Server virtual machine with network access to a SUSE Virtualization cluster.

Figure 1: Architecture Overview #

 

The technical components of the solution include:

Before you begin the deployment, ensure that the required infrastructure, software access, and credentials are available. This guide assumes that a SUSE Virtualization environment is available as the target platform for backup and restore validation.

4.2 Ensuring network access #

 

1. Make sure your firewall is configured to allow communication between the CloudCasa backup server and the SUSE Virtualization cluster nodes on port 443/tcp.

2. Defining a local A DNS record to for the VM that will host the CloudCasa backup server, such as 'local.cloudcasa.io'.

Note

The DNS record for local.cloudcasa.io must resolve to the SLES VM IP address across all client machines accessing the CloudCasa UI and any target Kubernetes cluster nodes. The local Envoy ingress server handles internal routing and TLS termination for CloudCasa traffic.

4.4 Preparing CloudCasa access and credentials #

 

Before installing CloudCasa Self-Hosted, ensure that you have the required credentials and license information. Do this by completing the following steps:

1. Obtain access to the CloudCasa Support Portal using your email address and one-time login code.

2. Download the CloudCasa license file from the Support Portal.

3. Obtain the following credentials from the CloudCasa team:

   • Helm repository credentials.

   • Azure Container Registry (ACR) credentials required to pull CloudCasa container images.

Important

Treat the Helm repository and container registry credentials as sensitive information. Follow your organization’s security practices and rotate credentials after completing the proof-of-concept evaluation.

This section describes how to prepare the operating system and deploy a single-node RKE2 cluster that will host the CloudCasa Self-Hosted services.

For additional product information, refer to the following documentation:

This section describes how to deploy CloudCasa Self-Hosted on the RKE2 cluster using Helm. The deployment includes configuring the required Kubernetes resources, creating the image pull secret, deploying the CloudCasa server, and configuring ingress to access the CloudCasa Web interface.

For detailed product information and the latest deployment guidance, refer CloudCasa Self-Hosted Documentation

After deploying CloudCasa Self-Hosted, configure the SUSE Virtualization environment as the protected environment. CloudCasa Self-Hosted runs independently on the RKE2 cluster and connects to SUSE Virtualization to discover and protect workloads.

7.3 Confirm the cluster is active #

 

1. Return to the CloudCasa UI.

2. Click Close on the Install Agent dialog.

3. Click Done in the Add Cluster pane.

4. Navigate to Clusters > Overview.

5. Wait for the cluster status to change from REGISTERED to ACTIVE.

   

   Figure 4: SUSE Virtualization Cluster Active in CloudCasa #

    

6. In the CloudCasa UI, navigate to Configuration > Storage.

7. Add your target backup storage location, such as object storage (for example, AWS S3 or Azure Blob) or file storage (for example, NFS or CIFS).

8. Ensure that the storage status is validated and active before proceeding to define and run backup jobs.

Note

Only after the cluster becomes ACTIVE can you perform backup, restore, replication, or migration operations.

To demonstrate that CloudCasa correctly protects and recovers a VM in your SUSE Virtualization cluster:

8.4 Validating the restoration #

 

1. Return to the SUSE Virtualization UI and navigate to Virtual Machines.

2. Confirm that the restored virtual machine appears in its original namespace. It starts in an Off state.

   

   Figure 13: Restored VM in Harvester UI #

    

3. Power on the virtual machine and open the console.

4. Log in and verify that data created before the backup is still present (for example, read back a test file written before the backup procedure).

   

   Figure 14: VM Console Showing Restored Data Verification #

    

This successfully demonstrates that CloudCasa correctly restored both the virtual machine definition and its persistent data.

Important

This does not validate Longhorn DR replication or the CloudCasa DR plan workflow.

The deployment described in this guide is intended as a proof-of-concept (POC) environment. For production environments, it is recommended to deploy a multi-node cluster with adequate memory resources and proper persistent volume (PV) storage rather than local-path storage. Additionally, authentication should be integrated with your organization’s authentication scheme, such as LDAP or OIDC. For further details, refer to the CloudCasa Self-Hosted Admin Guide.

This guide provides a reference design and guidance for a proof-of-concept deployment of CloudCasa Self-Hosted to provide data protection for virtual machines in an isolated SUSE Virtualization environment. Contact SUSE or Catalogic Software to explore production options to meet your unique business and technical requirements.

Copyright © 2000, 2001, 2002 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

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.
