As long as your disk backups are on a seperate system I would agree.
Backing up to a SAN for example. However in our case we don't have
that here and my disk backups are ending up on the same system as my
database is sitting on. And in the case of a total loss of your disk
array (what happened twice to us with RAID5 arrays) you just wiped out
your backups too. Even if you backup first to disk and then with
whatever tool to tape - in case of a total disk array loss you just
lost your most recent archive redos too. This is why I want to back up
at least the archive redos on a frequent basis directly to tape in
addtion having them on disk.
Anyway my problem is still not solved: any other input?
