Ricky,
The configuration that you are referring
to is what could be considered the 'Traditional' implementation of NDMP.
As you have found for yourself, there are a number of restrictions
on how the data can be managed though.
If you configure the NDMP environment
so that a Tivoli Storage Manager controls the data flow instead of the
NetApp Appliance, you have more options
This configuration will allow you backup
up to TSM storage pools (Disk, VTL, Tape), send copies offsite, because
the TSM Server controls the destination. You have the option to use
a traditional TSM Client utilizing the NDMP protocol or have the TSM server
perform the backup and restores using the BACKUP NODE and RESTORE NODE
commands. It a table of contents storage pool (disk based only highly recommended)
you can perform single file restores. you can also create virtual
filespace pointers to your vfiler that will allow you to run simultaneous
backups of the vfiler, that could shorten your backup and restore times.
Best Regards,

Ricky,
The Isilon uses the OneFS file system and TSM views it as one huge file
system. If backing up to disk, TSM will attempt to preallocate enough
space to back up the entire allocated space on the Isilon. Defining Virtual
File systems will not help because directory quota information is not passed
to TSM, and TSM only sees the total allocated space.
We were able to back up the Isilon to disk when we started on a test system
with little data on it, around 25 GB. When we attempted to implement
the same backups on a second, well-populated Isilon we ran into the space
allocation problem.
When backing up to tape, TSM assumes you have unlimited storage available
and is able to run VFS backups. We use Virtual File Space Mapping
(VFS) and back up to tape.
Refer to EMC SR#55554646, TSM PMR 23808,122,000.

Subject: [ADSM-L] Question about NDMP and TSM.
I have been asked to look into backing up our EMC Isilon using our TSM
server.
Everything I read, seems to point to backing this NDMP device to
tape.
Problem is, we do not use tape to backup production.
I have researched and found a few articles about backing the NDMP device
to tape but, there seem to be more cons than pros.
Is there anybody backing up a NDMP device to disk that can give me some
pros and, how they are using disk for this task.
I appreciate your time!
