Your backup command is: BACKUP NODE node-name virtual fs name MGMT=nnn MODE=FULL TOC=YES
I use 'TOC=P'. We have one file system where we cannot generate a TOC because of the number of files. TOC=PREFERRED will prevent the backup from failing when TOC creation fails.

This is mainly due to the size of the backups, ours range between 1tb - 25tb. If on disk, that's a lot of disk! For the server that ran the NDMP backups, we always had at least 2 drives defined to the data movers. Other activities such as normal B/A backups took place which required reclaim and migration tasks and had to share the drives with the NDMP backups. If i only defined one drive to NDMP and the drive was busy, the backup would fail. So at least 2, and 4 drives if the NAS filer had the fibre to allow it. One problem i had: because of the size of the dumps, we never had the time to make offsite copies of the tapes. Right or wrong (and i know it's wrong), i had limited resources in terms of drives and time. Lot's of different things with NDMP backups. These are a brief summary of my own notes. Define a domain for the NAS backups: define dom nas desc='NAS Domain' define pol nas nasp Now register a node: reg node node-name password type=nas dom=nas Obtain the IP address of the NAS filer: (From the NAS filer) ifconfig sm_vif Note the IP address Now define the datamover: define datamover datamover-name type=nas hla=ip-address lla=port userid=node-name password=password-of-NAS-filer dataf=netappdump (Note the format must be netappdump) (Note2: I kept the datamover-name the same as the filer-name - no point confusing things and keeps it simple) >From the filer: storage show tape Obtain the Alias name. Normally something like st0 and st1 Define the paths in TSM: def path filer-name drive0 srct=datamover desttype=drive library=xxxx device=rst0a def path filer-name drive0 srct=datamover desttype=drive library=xxxx device=rst1a (Note the device of rst0a and rst1a. This is the st0 and st1 taken from the filer and you need to suffix with an add 'a') q path Source Name Source Type Destination Destination On-Line Name Type ----------- ----------- ----------- ----------- ------- tsm-server SERVER AUTOLIB0 LIBRARY Yes tsm-server SERVER DRIVE0 DRIVE Yes tsm-server SERVER DRIVE1 DRIVE Yes filer1 DATAMOVER DRIVE0 DRIVE Yes filer1 DATAMOVER DRIVE1 DRIVE Yes (So now i see the 'normal' tape drive paths, plus the file ones) Define my devc: define devclass NASCLASS devtype=nas library=xxxx mountretention=0 mountlimit=drives estcapacity=1600g (this was an LTO4 library) And a stgpool: def stgpool <stgpool-name> NASCLASS poolt=primary acc=readw col=no reuse=3 dataf=netappd maxscr=2000 (Note the devc was the tape devc i just created. You can do this to disk, of course) And the mgmtclass and copygroup: DEF MGMT NAS STANDARD 1M SPACEMGTECH=NONE AUTOMIGNO=0 MIGREQUIRESBK=YES MIGDEST=SPACEMGPOOL DESC="NAS MC" DEF COPY NAS STANDARD 1M T=BACKUP DEST=stgpool-name FREQ=0 VERE=28 VERD=28 RETE=28 RETONLY=28 MODE=MODIFIED SER=DYNAMIC And finally: VALIDATE POL NAS NASP ACTIVATE POL NAS NASP I recommend you use a TOC (table of contents). See the admin guide or admin ref about this Set up a Virtual Filespce: DEFINE VIRTUALFS <nodename> <virtual-fs-name> <fs-name> <path> namet=server (Note: The fs-name and path must match that of the Netapp filer) (Note the virtual-fs-name is what TSM server knows the filer storage area as) This will backup the filer: BACKUP NODE node-name virtual fs name MGMT=nnn MODE=FULL TOC=YES THE BACKUP RUNS AS A PROCESS (not as a session) SO CHECK THE PROCESS TO CONFIRM THAT THE BACKUP HAS BEEN SUCCESSFUL! Notes: Q NODE will not show NAS nodes. Need to use Q NODE TYPE=NAS The Admin Guide states that Reclamation and Migration are not supported for these storage pools I am sure there may be better ways, perhaps dedupe etc, not sure. But this is what i setup Best of luck On 7 June 2013 08:51, Michael Roesch <[email protected]> wrote: > Hi everyone, > > we're planning on implementing a TSM server that also does backup > NetApp Filers and we've run into a few questions.
