By leveraging NBD’s ability to download multiple blocks in parallel, Xen Orchestra effectively reduces the impact of latency on backup speed. This optimization is especially beneficial for remote backups, where the backup repository is located far from the production setup.
- Strategy for Extremely High Latency Situations: For latencies over 50ms, Xen Orchestra recommends using XO Proxies for local backup and then it uses a process to mirror backup files with asynchronous transfer to remote sites. This approach ensures efficient backups even in challenging network conditions.
- Customizable NBD Connections: Users can now tailor the backup process to their specific needs by adjusting the number of NBD connections per exported disk. This customization is accessible in the Advanced backup job section, allowing for optimal performance based on individual network conditions.
- Advancements in On-Prem Immutability: Xen Orchestra is making significant progress in enhancing data protection, particularly with on-prem immutability. The upcoming feature aims to create a Backup Repository (BR) that is immutable for a predefined period, enhancing security against ransomware attacks. This feature, which is in the testing phase, allows for governance mode, enabling selected admins to modify immutability settings.
Overall, these enhancements in Xen Orchestra’s backup features not only improve efficiency and performance but also significantly bolster data protection and security. These developments are particularly relevant for organizations looking for reliable and robust backup solutions in diverse network environments.
6. Scoped tags
Xen Orchestra has introduced a new feature called “scoped tags” to enhance its backup and virtual machine management capabilities. This advancement focuses on refining the categorization and labeling system within the platform:
- Enhanced Categorization with Scoped Tags: Scoped tags provide a more detailed and context-specific approach to labeling and organizing resources. They are particularly useful in environments where similar tags are used across different projects or for various clients, but there is a need to distinguish the context more clearly.
- Context-Specific Labeling: For example, a generic “database” tag could be ambiguous in a complex infrastructure. Scoped tags address this by allowing for precise labels like “prod=database” for production environments and “devel=database” for development settings. This clarity ensures that resources are accurately categorized according to their specific use or environment.
- Flexible Application Across Various Scenarios: The use of scoped tags is not limited to just technical terms or environments. They can be extended to customer-specific categorizations or even incorporate emojis for a more visual and intuitive tagging system.
- Customization to Suit Unique Needs: The introduction of scoped tags offers flexibility and customization, allowing users to tailor the tagging system to fit their specific organizational and operational needs. This feature enhances the overall functionality of Xen Orchestra, particularly in managing backups and virtual machines in diverse and complex IT environments.
7. REST API enhancements
Recent enhancements to the REST API of Xen Orchestra have improved its capabilities and user accessibility. These updates focus on expanding the range of management options available via HTTP requests and streamlining the API’s structure.
Key Changes in the REST API:
- Expanded Endpoint Functions: The REST API now includes additional endpoints, allowing users to manage Xen Orchestra more comprehensively through HTTP requests. This expansion enhances the flexibility and reach of remote management capabilities within the platform.
- Access to Mirror, Metadata, and Config Backup Jobs: Users can now easily request information about existing mirror and metadata backup jobs directly through the API. This is achieved by performing simple GET requests to specific endpoints (/backup/jobs/metadata and /backup/jobs/mirror). This feature offers a straightforward method for monitoring and managing backup jobs, improving operational efficiency.
- URL Structure Updates and Redirections: There have been changes in the URL structure to optimize the API’s organization. For example, the /backups endpoint has been renamed to /backup. Additionally, the paths for VM backup and Replication jobs have been updated from /backup/jobs/:id to /backup/jobs/vm/:id. To ensure a seamless transition and maintain user experience, redirections have been implemented for each URL change, ensuring that users can continue to access the necessary functions without disruption.
8. XCP-ng 8.3.0 and XO Lite
The latest updates to Xen Orchestra (XO) and XCP-ng 8.3, even though they are not production releases as of yet, show enhancements to come from a user experience and system management perspective. One fo those is XO Lite, the lightweight version of Xen Orchestra.
XCP-ng 8.3 Features:
