vzdump support the following modes:
--stop
--suspend
--snapshot
I've tried them all on my VE.
While --stop guaranties consistent data, is there any advantage to using --suspend instead of --snapshot? Are backups with --suspend "more consistent" the --snapshot?
Since the running applications don't get told to flush to disk, isn't restoring a --snapshot backup equivalent to booting after a power failure?
If yes, is there some trick to make it "less risky" as a backup form?
