Re: [Veritas-bu] Backup Strategy

Sure! Investigate backing up to a disk appliance. There are a number
of vendors ... Data Domain might be a good place to start, as they have
much of the market.
Since you do nightly full backups, they'll love you and you'll be
impressed at what you can squeeze onto their disk (will vary with your
data and each vendor).
This isn't a no-cost solution, but I expect you will love the resulting
system. *No* tape handling on backups or restores ... what will you do
with all your spare time? ;-)
If you are considering "differentials", consider "cumulative
incrementals" first. More data is backed up, but restores may be
faster. Also, with either type of incremental backup, how much you can
fit on a tape depends on your data. If a few small files change ...
little tape; if a few huge files change ... maybe an incremental is
close to a "full"!
cheers, wayne (who knows a bit about NetBackup, but doesn't even know
how to spell BackupExec, let alone whether it can backup to disk).
