We finally gave up on NDMP entirely. We replaced it with NetApp's
SnapVault solution. Friendlier for the service owner to use, and
managing it all became Not My Problem.
When we did use NDMP with TSM, I zoned all the drives to the filers
(shared the drives with TSM and two arrays), but set a mou
I have noticed reclamation does not always start when volumes hit the threshold
and I do not use the de-dup option. I have found that if I re-set the reclaim
threshold that reclaim kicks off.
So for the example below run:
upd stgpool file-ve reclaim=20
No net change, but it seems to trigger the
We went the other route and backup our filers (Isilon and BlueARC, not
NetApp) over NFS using a pool of TSM proxy nodes and schedules that
"float" between the nodes. We have a small staff relative to the size of
our environment, and decided that while we could support one backup
environment well, w
To paraphrase Churchill, NDMP is the worst form of NAS backups, except for all
the others..
I keep testing snapdiff with every new TSM client and/or ONTAP update. It's
just not as reliable as NDMP for me.
Bottom line is that if you can't handle the periodic full-scan backups (like
journaling)
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.

If you have a NetApp, is there any particular reason you're not using snapdiff?
My experiences with NDMP are all bad. Troubles with reclamation, troubles
with creating copy pools, having to cancel backups, reclamation and backup stg
because the recovery log was getting way too full.

You can use disk or tape. Disk can be used through a VTL or as a normal file
device class.
If you want to use file device classes, look in the manual for "backup up a NAS
file server to native pools"

He is talking about a "3-way" NDMP backup introduced with NDMP v2.
It lets you use a second file server as a remote storage agent.
File Server 1 --> LAN --> File Server 2 --> Local/SAN attached tape drive.
The following thread discusses it, but I never got it working and I don't think

Hi Michael
I believe the backups can be stored on either disk or tape, but i only ever
use tape. 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

Hi Wanda
From personal experience my reclaims show a similar behavior, and from
what I understand that used tape count will keep on increasing. The amount of
time it takes to dehydrate data from disk to copy when doing a reclaim will
impact the reclaim operation and of course the amount
Hi everyone,
we're planning on implementing a TSM server that also does backup NetApp
Filers and we've run into a few questions. Hope that you can help me with
these.
1. Is it possible to store the NDMP backups on disk or is only tape
possible?
2. If only tape, how many drives are recommended for
Hi Grant,
What do you mean?
You can backup a NetApp direct to Tape but still keep track in TSM.
