My Filr 1.1 environment consists of 2 Filr appliances, 1 Microsoft SQL Server, and 2 Search appliances running on VMWare. For the appliances, 1 disk is attached using Independent and Persistent settings. The backup software we use to back up our virtual machines (Veeam) does not support the backing up of this disk type since it makes snapshots of each virtual disk (Independent disks do not support snapshots in VMWare).

My question is whether this disk type is necessary for the appliances to run; can they be changed to be non-independent?
