You can only do 9 incremental levels of backup on the NetApps with NDMP. I haven't used that SET UPDATE directive before (or the SET LEVEL command I detail below - I run a weekly full on my volumes, so 9 incremental's is enough), but just a quick run down:
There are 10 dump levels for NetApp NDMP (0-9). A level 0 dump covers everything in a volume, a level 1 covers everything newer than the dumpdate for the last level 0, a level 2 covers everything newer than the last level 1 etc up until level 9. A Netbackup full backup schedule runs a level 0 dump A Netbackup cumulative schedule runs a level 1 dump A Netbackup differential schedule runs a level n+1 dump, where n is the last dump level recorded against the volume (NB: at the filer! - if someone is using ndmpcopy / doing level 0 dumps to null, this affects the last recorded dump level) You can use the directive "SET LEVEL = 7" (as an example) to force a specific level. Depending on how complex you want your policy configuration, you could set up your monthly full, then potentially use an NDMP level per half week (ie week0 - 0.5 SET LEVEL=1; week 0.5 -week1 : SET LEVEL=2 .... week 4-4.5 SET LEVEL=9) but that's going to need 9 policies.

I have been able to get what appears to be "cumulative" dumps/backups of our NDMP paths by setting the SET UPDATE = Y entry at the beginning of the policy include list. However, I want want to perform differential backups of the paths, ideally, a once monthly full, followed by daily differentials the remaining days. Anyone have any tips?
