VMware Backup Policy - Full / Inc

Dears,

we are running VMware backups with Daily Full - Accelerator Enabled. will it make sense if change this backup method to incremental. if yes, is there any advantage in Backup window and Backup Size. also need to know VMs can be restored from incrementals without restoring in sequences (full...inc...)

Thanks in advance.

    You won't be taking advantage of Accelerator with only full backups scheduled as they will all do a forced rescan. I would suggest reading up in the NetBackup for VMWARE documentation, I would link it but you haven't stated what version you're using.

    In summary for best practice I would say you need the following schedules; Full (Forced Rescan), Full and then an incremental that best suits your other configuration settings. If you don't have a seperate Full backup schedule with Forced Rescan enabled then all your full's will perform this regardless.

    In answer to your second question you can perform full VM restores from incrementals if you have Block Level Incremental Backups (BLIB) enabled and your backup target is MSDP. BLIB does not play well with tape.
