You have to setup Cumulative incremental I believe as ndmp backup levels go to 9. After 9 every backup is a full backup unless reset. Cumulative incremental resets it so you'll get a differential next. This is the case on NetApps.

NBU version is 6.5.3. Did Complete Fulls, with all of the /ifs/projects/ areas in the Backup Selection, starting on 11/26. This past weekend I kicked off Differential Incrementals for the same Backup Selections. All of the areas in that /ifs/projects appeared to have completed as expected except for one. With this one (10+TBs, 1,643,099 files) during the backup NBU said it was doing a Differential, but when it was all done, it had actually backedup everything again. I can go into Backup and Restore for this client, and choosing "show all backups", it will show the Full that was started on 11/26 and will also show the Differential that was started on 12/6 with the same Modification date (prior to 11/26) for each. Wouldn't have noticed so much, but with it taking 4+ days and using 16 tapes, has got me wondering about it. If I kick off another Differential this coming weekend, I certainly don't want to have yet another backup that gets all of the data once again. Any thoughts? Thanks, Randy
