XenServer offers a range of features to enable you to protect your VMs and vApps.

VM Protection and Recovery (VMPR) - scheduled snapshots

XenServer VM Protection and Recovery (VMPR) provides protection against loss of individual VMs by taking regular scheduled VM snapshots which you can import back into XenCenter and use to recreate the original VM if it is corrupted or inaccessible.

Important: VMPR and its functionality has been removed from XenServer version 6.2.0 and higher. Applications, code, or usage that depend on VMPR will not function in XenServer version 6.2.0 and higher. The VM snapshot functionality and functionalities that depend on VM snapshot (other than VMPR) remain unaffected.

High Availability (HA)

XenServer High Availability (HA) provides protection against downtime of critical VMs caused by the failure of individual servers in a pool by guaranteeing that VMs are automatically restarted on an alternate server in the same pool, with minimal service interruption. The pool database is constantly replicated across all nodes and is also backed up to shared storage on the heartbeat SR for additional safety.

Disaster Recovery (DR)

XenServer Disaster Recovery (DR) provides protection against the loss of multiple servers at your primary data site. With DR enabled, the pool database is constantly replicated via mirrored storage, and in the event of a disaster at your primary site, VMs and vApps can be recovered from the mirrored storage to a pool on a secondary (DR) site.
