Considerations and Limitations

When you plan to use Veeam Plug-in for Xen, keep in mind the following limitations and considerations.

Configuration

When configuring Veeam Plug-in for Xen, consider the following:

The Xen pool must be able to establish a direct IP connection to the backup server. Connections through NAT gateways are not supported.
After you make changes to your Xen environment (for example, you migrate a VM between cluster nodes), these changes may not appear in Veeam Backup & Replication immediately. The data synchronization process between the backup server and the Xen pool may take up to 15 minutes to complete. You can speed up the data synchronization process by rescanning the Xen pool.

Backup Repositories

When managing backup repositories, consider that Veeam Plug-in for Xen does not support storing backups in Veeam CLoud Connect repositories. However, you can use them for storing copies of backups created with Veeam Plug-in for Xen.

Workers

When configuring workers, consider the following:

Veeam Plug-in for Xen requires at least one worker deployed in the same pool where protected VMs reside.

The worker image is stored in the storage repository where it was initially uploaded.

Backup

When protecting Xen resources, consider the following:

Veeam Plug-in for Xen does not support VM replication.
Veeam Plug-in for Xen does not support guest quiescence.
Veeam Plug-in for Xen does not support RAW disk processing. To back up VMs with RAW disks, manually exclude these disks as described in section Step 3. Configure Backup Source Settings.

Restore

When restoring Xen resources, consider that Veeam Plug-in for Xen does not support entire restore of a Xen VM to the original location if the original instance exists in the cluster in the Locked state.
