About 2 years ago our department purchased a f740 for use as a /var/mail spool. Our main backup infrastructure is based on some tape robots and a solaris box running legato networker. We have not been real happy w/ backing up out netapp on legato. Legato was chosen many years ago due to the user available 'recover' command, which is critical w/ 25k+ users on some of our servers.
- BudTool
We have not tried this.
- NFS
This is what we are currently using. This is not great since the atime of mboxes is modified, confusing the users who constantly 'finger' each other to see who has read their mail.
- NetWorker NetApp Client
We spent a lot of time on this, with bad results. The filer would crash, the dumps would stop. The filer wouldn't start dumping again the filer was rebooted. We pursued the problems w/ both legato and networker with frustrating results. Legato told us to wait for next legato patch, or maybe next version of ONTAP. Netapp would tell us to upgrade version of ONTAP or perhaps wait for next legato patch. After several months and 3-4 iterations of this cycle we gave up. It seemed that neither tech support were really interested in the problem.
- NDMP-compliant NetWorker
We recently got legato 6 w/ ndmp support, and a sun e3500 + qualstar 412600 jukebox to test this option. Our backup guru's first attempt to connect to the f740 did not work for some reason, so I am going to read through all the legato docs ASAP. It would be nice if we could reliably backup up our netapp to a jukebox mounted off a sun (not attached to the back of the filer) using NDMP.
It is too bad we had such bad luck with option 3. The filer has performed fantastically, but our backup woes always come up when we discuss replacing old NFS servers.
It would be interesting (to me at least) to hear experiences with each variant. Option 4 is essentially replacing option 1 since that option is being discontinued.
Cheers, Grant

Anybody have any bad or good experience using legatto as backup for the net app filer?
