Yes,

Novell is a problem for fast full restores.
But you can achieve the same effect as full backups of consolidating your active
data
by creating backupsets.
This avoids that nasty growth problem in the database.

Adam,

We were only doing incrementals and we had a situation where we had to restore a
Novell server.
The restore had to go through two years worth of incremental tapes to complete
the restore. I would
strongly recommend doing periodic fulls (and colocation) unless you have a SLA
which allows for extremely long restores.

Hey,

Our management is wondering if it's safe to just do incrementals
forever, or whether we should try to do a forced full every few months
to keep things fresh.  Our experience has been that the incremental
system works great-- we once restored a whole raid 5 array, with many
files from years ago.  But, nonetheless, I'd appreciate any stories or
testaments to help build a case.

Thanks much,
adam
