Hi

First check compatibility with IBM and EMC.

Using NDMP negates all of this and reduces the functionality.

- you can't use NDMP to back up part of it.
- The time it would take to do a full backup.
- The time it would take to do a restore.

That said if your data is small then these probably don't matter so much.

I found out that this is true a long time ago, but it does not stop you from 
manually doing a move data to empty out a tape volume.  It is just a very 
manual form of reclaim.

And as a bonus, ndmp storage pools cannot be reclaimed and this means that
they hold tapes until the last data has expired.  TSM format storage pools
can be reclaimed, and if they are file storage pools can be deduped as well.

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!
