We keep toying with the idea of NDMP, but there are some big cons in my
opinion to using the NDMP protocol.
1. No way to make copypool copies of data backed up through NDMP. Does
not meet our DR requirements.
2. All data in an NDMP session is bound to the same retention. No way to
"slice & dice" the backups so you can retain certain files for only a
few days and other data much longer. This causes issue #3...
3. Full-incr-incr...-Full backup methodologies can cause you to keep a
LOT more data depending on your longest retention.
4. TSM's implementation of NDMP backups for q-trees/volumes is really
manual compared to other products we looked at (Bakbone for one).
Those flaws keep us from implementing NDMP in our production
environment. We have expressed these shortcomings to IBM and they have
indicated that in the next major release of TSM in Q1 07 that they will
have "better integration with NDMP and the TSM storage hierarchy". It
sounds like perhaps they will address issue #1 in my above list so we
can resolve the DR issue.
Perhaps we will make another stab at NDMP at that time, until
then, we continue to back the Netapps through NFS mounts whenever
possible and through the painfully slow CIFS protocol when Windows ACLs
need to be captured.

Jeff,
Why not look into backing up the NetApp via NDMP?

Hi,
We have:
TSM Client 5.3.2 running on Windows 2003 TSM Server 5.2.4 running on AIX
v5.3.01 FAS960 running data ontap 7.0.2
I know something similar has appeared here earlier and that Pete
Tanenhaus provided a response. But....
Our DSM.OPT file contains
DOMAIN ALL-LOCAL " \\FILER\SHARE\FLDR\* "
INCLUDE " \\FILER\SHARE\FLDR\*.* "
On the windows 2003 server, we map the above share to a drive (example
Z:).
Using the DSMC command, i can back this up fine. Using the GUI, i can
also back this up fine. However, when using the scheduled service, it
failed with message ' ANS1071E Invalid domain name entered: '
\\FILER\SHARE\FLDR\* '
Our Windows admin guy has changed the account under which the scheduled
service runs (from 'system') , to use an account which is a domain
administrator. But it still fails with the same error.
Any idea?
Thanks.
