Hi Jordan,
With a (directly attached to the NetApp) tape device you will need to run an NDMP-compliant application such as CommVault's Galaxy (or use rsh scripts) to run dump on the filer. Anyway the resulting format written to tape is in the BSD dump format which is compatible with Solaris' ufsrestore.
To restore them to a non-NetApp target location you can perform a native (to Solaris) ufsrestore of the backup, but there will be a few hoops to jump through, such as, knowing where the backup images are on each tape and running the tapes through dd prior to ufsrestore. The reason for this last point is that NDMP backups even though they may cross tape boundaries are actually written as one very large (usually) data stream and therefore have to be read back that way which an NDMP restore on a filer achieves.
If the data in the backup has mixed (Unix & NT) permissions then the NT permissions will be lost during a ufsrestore backup, but the data & unix permissions will be intact.
Alternatively you can perform non-NDMP backups over CIFS which will capture the data + Unix & CIFS permissions. If you then restore on a filer it will restore the data + Unix & CIFS permissions. If you restore on an NT server you will get the data + CIFS permissions, but no Unix permissions. I'd go this way if you only have CIFS data or mixed data and I'd perform NFS backups if you only have NFS data.
However, it really looks like the dependency is on the equipment at your disaster recovery location and in this case I'd go for filers! ;-D
Hope this helps and I hope CommVault are listening.
Cheers, Grant

We're currently planning to purchase a NetApp 720 in the next few weeks. Thus, we are evaluating our backup options for this product.
Basically, what I want to know is if anyone has experience with CommVault's Galaxy product and using it with a (directly attached to the NetApp) Treefrog tape library.
What we want to be able to do is take the tapes produced by backing up (the NetApp) via NDMP, and restore them to a non-NetApp target location. We want to do this so we can restore our data (in event of disaster) without having to have a NetApp to restore it onto.
Anyone have any experience with this, or know if it is possible? I'm having little luck getting assistance from CommVault. :(
Thanks, Jordan
