10.5 XenServer deployment guide
With Unitrends Backup deployments, the appliance’s initial disk stores no unique data or backups. Storing this data on different disks or external storage arrays enables you to reattach the storage to a different Unitrends Backup appliance, so you can retain your original appliance’s settings and backup data if you need to deploy a new Unitrends Backup appliance.
This deployment guide includes instructions for deploying using new storage and for deploying using storage that contains existing backup data from another Unitrends Backup appliance. The process is similar for both deployment types, and the applicable sections cover any variations.
