3 What is XenServer VM Protection and Recovery? XenServer's VM Protection and Recovery (VMPR) feature provides a backup and restore utility for your critical service VMs. Regular scheduled snapshots are taken automatically and can be used to restore individual VMs. VMPR works by having pool-wide VM protection policies that define snapshot schedules for selected VMs in the pool. When a policy is enabled, snapshots are taken of the specified VMs at the scheduled time each hour, day or week. If configured, these snapshots can also be archived automatically to a remote CIFS or NFS share, providing an additional level of security. Several VMPR policies may be enabled in a pool, covering different VMs and with different schedules. A VM can be assigned to only one policy at a time. Note: The VMPR feature is available in Citrix XenServer 6.0 Advanced Edition or higher. To learn more about the features available in different XenServer editions, visit: Creating a VM Protection Policy Before starting this procedure, make sure the pool contains a storage repository (either a CIFS ISO library or NFS ISO share) where want to store the snapshot archives. You will need to reference the path to this SR to archive the snapshots and, for CIFS, the credentials. Note: If the pool does not have a CIFS or NFS ISO storage repository, click the New SR button.

Note: A VM can be assigned to only one policy at a time, so if you assign it to the new policy, you are prompted to remove it from its current policy. 5. Select the type of snapshot you want to use for the scheduled snapshots: Disk-only snapshots store the VM's disks (storage) and metadata. They are crash-consistent and can be performed on all VM types, including Linux VMs. Disk and memory snapshots save the VM's disks (storage), metadata, and its current memory state (RAM). Note that this type of snapshot can be very large. 6. Create a schedule for the snapshots and specify the maximum number of snapshots you want XenServer to store. Page 5

6 7. Configure when and where you want snapshots to be archived, and click Test. Note: The archive and snapshot schedules do not need to match. However, you cannot define an archive schedule that is more frequent than the snapshot schedule. 8. Enter your address to receive s when snapshots are created, archived, or if these operations fail. 9. Select the Run the new VM protection job when I click Finish check box, and click Finish. Page 6
