Re: Experience / Best Practices with long time VM snaps for huge VMFS stores?
From Richard Anderson:
Why not suggest Avamar for incremental-forever deduplicated backups of the VMs. Even can do an incremental restore using block change tracking for fast recovery to a previous backup.
Just run a new incremental backup before a change and you are all set, no snapshots to worry about, no performance problems when it's time to cleanup snaps, or disk space consumed on the datastore, plus it's an actual backup and can be replicated offsite for DR recovery.
