Hi

First check compatibility with IBM and EMC.

Ron has mentioned a solution that applies to NetApp that may not apply to EMC 
isilon eg. isilon does not have a vfiler concept.

I found that the restrictions of NDMP did not warrant the effort to use it on 
something like an isilon cluster.
The benefit of isilon is the size you can grow them to and the bandwidth you 
have to storage with multiple nodes.

Using NDMP negates all of this and reduces the functionality.
- you are limited to the bandwidth a single host(TSM server) and single isilon 
node can service.
- There is no incremental only differential. There is no snapdiff type 
functionality that NetApps have
- 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.

One other niggle is that you need a windows machine to do a graphical restore 
(Web/Java UI).

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