Recovering Backups from an Unavailable PHD VBA (Citrix XenServer)

SUMMARY

On Xenserver how to recover backups from an unavailable PHDVBA

ISSUE

If your PHD Virtual Backup Appliance becomes unavailable for some reason, you can still access your backups by deploying a new appliance and pointing to the previously used storage repository or attaching the existing virtual disk used to store backups.

To recover backups if using an attached disk

  1. Open XenCenter and select the problematic PHD Virtual Backup Appliance. If running, power off the appliance (right-click and select Shut Down).
  2. Click the Storage tab, then select the virtual disk used to store your backups, for example, PHD Virtual Backup Store.
  3. With the disk selected, click Detach.
  4. Deploy a new appliance. Use the XVA that came with your initial installation package. Follow the steps in the installation guide for details.
  5. Before powering on the new appliance, instead of creating a new virtual disk for backup storage, use the virtual disk you detached earlier. With the new appliance selected, click the Storage tab.
  6. Click Attach...
  7. From the list of available disks, select the PHD Virtual Backup Store you detached earlier.
  8. Power on the appliance. You can begin backing up and restoring VMs once again and all backups stored previously should be available in the backup catalog.

To recover backups if using CIFS or NFS

  1. Power off the problematic appliance within XenCenter.
  2. Deploy a new appliance using the XVA that came with your installation package.
  3. Follow the steps in the installation guide for details, making sure to select CIFS or NFS as the storage type.
  4. Enter the path to the existing backup data store used by the problematic appliance.
  5. Click Save, then restart the appliance.
  6. The appliance recreates the backup catalog automatically and you can begin backing up and restoring VMs using the new PHD VBA and the existing backup data store.
