I know this thread has been quiet for a few weeks, but a couple of observations...
1) We back up /vol/voln/.snapshot/hourly.0. Obviously we can't restore there, so we have created /vol/voln/restore on each volume. We restore to any of these dirs on the filer. The restore goes in /vol/voln/restore/original path (without the snapshot... path). Not quite an alternate path restore, but close enough for us :-).
2) The only time we have seen a tape drive problem reboot a filer is if we are messing with a tape drive (like trying to jiggle loose a stuck tape). Other than that, we have never had a tape drive problem reboot our filer. Maybe NetBackup does not keep trying like Budtool.
3) In 3.2 you can backup to another filer (three way backup). It's pretty cool... some of our filers have only one tape drive, and others have two. We have set the filers with one trap drive to use only their own storage units, and the filers with only one tape drive are set to any available. So... if a filer with only one tape drive has a tape drive problem, it will go backup on another filer... at a 50-60% performance hit, but at least there is a backup. This took a little getting used to when we first upgraded to 3.2 when we had filers backing up all over the place. I am hoping to see a more granular selection (or ranking) of storage units from NetBackup in the future. There is one filer with a little bitty robotic tape library in another building who should not ever be used for another filer's backup. I can't prevent that from happening if I have it set any set to "any available".

I've been told that NetBackup can only restore NDMP dumps in place, too -- not to an alternate directory, for example (I haven't verified that with the vendor).
QuickRestore 2.6 can restore an NDMP backup to an alternate *root* path, if I understand the documentation correctly. If you backup /depot/src as a single set, and you want to restore just /depot/src/utilities/billing, you can put that into /otherdir/utilities/billing, but not /otherdir/billing (i.e., the directory pathname beneath the root of the backup must be preserved). A quick call to Workstation Solutions should clear that up, or I can dig out the manual when I'm back at the office on Monday.
