Protecting VMs and vApps

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

High Availability

High availability protects against downtime of critical VMs caused by the failure of individual servers in a pool. This feature guarantees that VMs are automatically restarted on an alternate server in the same pool, with minimal service interruption. XenServer constantly replicates the pool database across all nodes. The pool database is also backed up to shared storage on the heartbeat SR for extra safety.

Disaster recovery

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 through mirrored storage. If a disaster occurs at your primary site, DR can recover your VMs and vApps from the mirrored storage to a pool on a secondary (DR) site.
