Yepper. On volumes with lots of files, that ndmp history/catalog pass can be crazy!
I once tried to use ndmp backup on a volume with 500,000+ files. After 8 hours and a huge load (FAS6080) the ndmp gave out and quit. Eight hours of building the index and it didn't finish.

We used NDMP and Symantec NetBackup. Was pretty decent setup, but does put a load on your filer.

Without back up software, I think you can only control a drive, not a robot. Somebody can feel free to correct me if I'm wrong, I've never tried anything else.

We’ve recently purchased a Dell TL4000 with 2 x LTO7 drives and 24 tapes. We have a four-node cluster running 8.3.2Px and for now we’re directly connecting the TL4000’s A-side FC to node 1 and the B-side to node 3. AFAIK the device itself is set up correctly and all the physical and virtual status LEDs and are happy.
After installing the correct TCF file, ‘sysconfig –t’ run against the directly connected nodes shows the drive as supported (IBM LTO-7 ULT3580) with all sorts of device name permutations (rewind, no rewind, unload, etc). Running ‘storage tape show’ shows two tape drives, one per directly attached node, named st0 and a media changer on node 3 named mc0. The tape drives are offline, the media changer is available.
I’ve played with the various ‘storage tape’ commands but am making no headway. I’m sure the docs are out there, and I’ve looked through the NetApp documentation as well as Googling for a while, but don’t see a way to control the media changer to, for example, tell tape drive 1 to load slot 6, and then another command to dump a volume to it. I understand we want SVM-scoped ndmp. Does anyone have bare bones examples using ndmp or some other local utility? If we need to purchase something like Tivoli or Netbackup or CommVault etc then I guess we will, but we’d prefer free.
Thanks!
