Content preview: I have stayed away from NDMP because it seems that it locks
you into a particular vendor - if you use Isilon NDMP for backups, then you
have to use Isilon NDMP for the restore. In a major disaster, I would be
worried about the hassle of procuring compatible hardware/software to do the
restore. We instead divide our Isilon storage up into separate NFS
mountpoints/TSM
filespaces and then point the client schedules at them with
"-domain='/ifs/dir1
/ifs/dir2'". We backup a 2PB OneFS filesystem in this manner, with ~200
million
active files. [...]

We actually are moving away from Isilon for cost reasons though, and moving
towards GPFS. mmbackup removes a lot of the workload division complexity,
though adds other complexity at the same time. That said, it just invokes
dsmc behind the scenes, which means that we can restore our Isilon backups
to GPFS, and vice versa.
