So is ANYONE satisfied with any 3rd party NDMP colutions? IT's a nice fast protocol.. but I'm not seing a lot of support...

Is the major advantage with NDMP (besides speed) that it backs up both your ACLs AND your UFS file permissions? Is there any other wayt o do this?

Has anyone tried using Budtool to backup a netapp?

Yup.  We've been using BudTool to backup our F330 for about 5

months. We spent a month or two working the kinks out of it before we let it touch our filer. Here's what we found:

1) BudTool's reporting is horrible.  End of story.  Anyone who
   tells you otherwise is either deranged or hasn't actually used
   the product.  Fortunately, if you know Perl, writing a script

to parse the logfile and send out a readable report (and page on fatal errors) is fairly trivial.

2) BudTool's built in scheduling could only have been written by a
   fool who liked GUIs and never actually had to support a backup
   solution in a production environment.  cron and a small shell
   script handled this problem.  (AMANDA has the best backup
   scheduling in my opinion.  Someday there'll be a vendor who
   picks up on it.)

3) User level restores aren't supported for NDMP and only work for
   UNIX clients if your willing to throw security out the window.
   When doing a restore via NDMP, the destination for the restore
   has to be on a filer.  If your users need to be able to restore
   data from tape, pick another product.  If you're willing to

pull stuff off tape for them (the GUIs not bad, but not great either) occasionally, then you'll be ok.

4) Having one BudTool server control a directly connected 100 tape
   DLT400 jukebox, a 5 tape stacker connected to our F330, and a 5
   tape stacker connected to our research departments number
   cruncher is pretty nifty.  Having all the tape and file
   histories in one place is nice too.

5) BudTool has a utility called btcp which will copy all your most
   current backup requests (Lev 0s and all necessary incrementals)
   to a set of tapes for offsite storage.  It doesn't just dd a
   bunch of tapes.  Very nice.  Unfortunately, btcp is a little
   brain-dead and tries to copy _all_ the requests to one set of
   tapes.  If you have a couple hundred GB worth of backups, this
   can take a really long time.  Again, a little shell script

fixed this problem.

All in all, I don't think I've ever been 100% satisfied with any

software product. But BudTool gets the job done (with a little help).
