Hi everyone,
thank you for your input, especially Jeff White for his very detailed
message :-)
So it seems like, some have NDMP working and some don't and now I'm not
sure which road to take.
Independently from which way you go (NDMP, SnapDiff,...), are 2 drives
sufficient for that or is it bett
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
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"

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
