Reinstating a failed PxM Virtual Appliance

This section covers:

Backup and restore overview

The PxM Virtual Appliance restore procedure requires a backup file so it is important that regular backups of the PxM Virtual Appliance are taken and kept in accordance with your corporate recovery strategy. This will enable a PxM Virtual Appliance to be restored from a backup when a system failure occurs.

If your PxM Virtual Appliances are in a clustered environment we strongly recommend that VM level backups are performed on all nodes. Once the node has been reinstated it will automatically catchup at the next synchronisation interval.


A PxM Virtual Appliance generated backup file is a backup of the leader node only and can only be used to rebuild a new cluster leader.

If you restore the PxM Virtual Appliance backup file you are building a new cluster with a new leader node on it's own. You will then have to recreate all follower nodes from scratch and join them to the new cluster.

For this reason we strongly recommend that VM level backups are performed on all nodes


Session recordings are not included in a VM level backup file or a PxM Virtual Appliance generated backup file as they are saved to an external file store.

The restore process allows you to reinstate your existing PxM Virtual Appliance configurations onto a new PxM Virtual Appliance using a VM level backup.

Upgrade and restore paths

The following table provides an overview of the upgrade and restore paths depending on the version restoring from and to, and also which upgrade path requires a backup/restore as a straight upgrade is not possible due to the changes in the system.

The links in the table will take you to the corresponding upgrade and restore procedure.

If you are unsure which is the correct upgrade and restore path for your environment please contact Osirium Support for help.
