Hi David and Wanda, We're planning to use another data mover on each ESX cluster to backup the data mover that does the snapshots. The main advantage we see is that the restore would be simple, and it is unlikely we would restore single files to it -which using a regular client backup would provide. The downside is having to create and maintain 12 new data movers whose only job right now is to backup one small virtual machine each. The extra data movers may get more work to do in the future if we split up cluster backups among more than one data mover. We didn't think very far or very deeply about this question, and may change solutions after more experience clarifies the merits of the alternatives.
Either should work, and it should be easy to switch. So my priority is to get a backup, any backup working. Keith
