Recommended approach to VM backups
Having now moved to BE 2012 VRay I'm just wondering what the recommended approach to VM backups is?
We have around 15 running VMs across 3 ESX hosts (with vCenter) plus another 8 powered-off VMs which we use occasionally. Total backup size of these VMs in BE 12.5 (ie data level backup) was around 3.5TB. Haven't run any backups in 2012 yet - just building up my jobs to run tonight.
We used to do Full Friday backup then Incrementals Mon-Thu, both B2D then Duped to Tape.
Should I continue doing Full Fridays then Incremental daily backups of ESX, or will that cause issues with restoring - should I only do full ESX backups?
Does this / how does this affect dead-server restore to an alternate VMware system only used for DR purposes?
