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.

Sent by: "ADSM: Dist Stor Manager" <ADSM-L@vm.marist.edu> 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.

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.
