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.

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. -- Skylar Thompson (skyl...@u.washington.edu) -- Genome Sciences Department, System Administrator -- Foege Building S046, (206)-685-7354 -- University of Washington School of Medicine On 02/ 1/13 07:48 AM, Rick Adamson wrote: > Our AIX admins are building a multiple node GPFS cluster and mention the > desire to use the "mmbackup" command to accomplish backups to TSM. > In reading over the manual I find no mention of it, but searching IBM support > there are plenty of docs which I just started reading. > My question is what is the preferred way to do this amongst those who have > dealt with it? > Win 2008 with TSM Server 6.3 > AIX 7.1 with BA client 6.3 > > All comments welcome.... > Thanks ! > ~Rick >
