IBM has an apar open fix a performance issue with mmbackup; see IC86976.

We are seriously looking at gpfs to replace our current file server on Netapp.

Prior to the v6 snapshot enhancements it would take 4 days to do a backup
of the fileserver via the b/a client over cifs.  With the snapshot enhancements
it takes about 3 hours most nights.  I wouldn't want to go back to walking
the tree every night even with a faster walker.  I hope the mmbackup will work.

mmbackup is part of GPFS, not TSM. There's some docs here:

http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=%2Fcom.ibm.cluster.gpfs.v3r5.0.7.gpfs100.doc%2Fbl1adm_mmbackup.htm

We experimented using mmbackup, but found it didn't scale well and had
some reliability issues. We ended up partitioning our data up into
separate directories, and backing those up as separate filespaces using
the standard dsmc. That worked much better.
