Combining full VM backups with differential backups
One limitation that I have encountered in BE, which I think other users have encountered as well, is that it is not possible to combine full VM backups with differential backups.
For example: I have a 1 TB (Terabyte) file server.
In my weekly full backup, I want to make full VM backup (VMDK backup using VCB), so that I get a very fast DRP should my VM be destroyed (just restore the VMDKs and click "play").
In my daily differential backup, I want to make a file level backup of only files that changed since the last full VM backup (differential).
Even with the latest version of BE (2010), this is not possible because VMDK backup does not set the archive bit.
I have tried the option "differential - using modified time", however, this does not work either because it requires the full backup and differential backup selection lists to be the same (this is not the case because, as stated, full backup is VMDK and differential backup is file-level).
So, I am forced to make a compromise. I have two options:
1) Backup full VM everyday: good DRP but impractical since the backup takes too long and uses too much tape (1 terabyte per day).
2) Do standard file level backups (full weekly + differential daily): ok from the backup time / tape usage perspective, but my DRP is rubbish (requires a lot of manual operation).
Anyone else thinks this would be a nice feature?
