Sorry, yes I meant Cumulative Incremental Backup. =20
=20
Thanks for everyone's opinions and experiences.  I really like the plan =
to upgrade to NBU 5.0, using disk for the primary copy, and in-line tape =
duplication for off-site and archive.  We are looking at a new =
directions of some sort anyway.  We're currently using STKL180 and STK80 =
robots with Quantum220 tape drives and SDLT tapes.  The problem is they =
aren't making Quantum220s anymore.  This is bad when trying to keep =
everything compatible,  - tapes, drives, DR site with production site, =
duplicates.
=20
Thanks again.

You specified you are doing cumulative differential backups. Did you =
mean Cumulative Incremental Backup? The Cumulative will backup all files =
that have changed since the last full backup. As the week goes on you =
incremental should be getting larger. This is good, considering for =
recovery you only need one full image and the last incremental backup. =
But on the other hand each day processing time can get longer depending =
on the additional amount of data that needs to be backed up and =
duplicated.  =20

=20

I do Differential Incremental backups during the week. This will only =
backup data that has been changed since the last backup, Incremental or =
Full. Less time to backup and duplicate. Down fall, for recovery you =
need the last full and all incremental tapes after the full. It's a toss =
up...=20

=20

Yes do set the -mpx parm on your duplication process. It will save you =
loads of time.=20

=20

I once had Vault running here but until I found it was not duplicating =
all of my images we threw it out. I them developed my own duplication =
programs using the base set of CLI program of NetBackup.  =20
