The only issue I have ever ran into is with Networker. If you need to a restore for more than 1024 files you can not use DAR. The work around is to turn off DAR, rerun the restore and it works fine. Just keep in mind the restore will be slow because you will have to walk through the tapes sequentially until the files are fond.

What kind of problems are you having? I have not had any major issues with either Networker NDMP or Netbackup NDMP. Both work well, although Netbackup does not have DAR capability yet.

Most of the folks we deal with have a lot of problems with NDMP. It would certainly be helpful if you could provide the list with some of your tricks to make NDMP work consistently.

Go with NDMP on Legato. As others stated, NDMP and Legato work very well. I have setup a few environments with Legato Networker and NDMP via Netapp. The nice thing about NDMP is you directly dump off the Netapp to tape which is very quick. It will push LTO and SDLT tape drives to the full performance capabilities. In addition, the CPU overhead required to do a NDMP backup vs over NFS is much lower on the Netapp. Keep in mind though that the tape drives dedicated to the Netapp for NDMP can not be shared by other non Netapp Legato clients/storage nodes/servers (can be shared by other Netapps though).

Dear Toasters,

I was wondering if any of you guys were using Legato for backing up your NetApps. I currently have 2 filers that i am backing up to a Legato server running Solaris 2.8 over NFS. I mount the NetApp volumes onto the legato server and then backup those mount points.

I am not sure this is the best thing to do in terms of performance.

Is there an alternate, easier solution.

Thanks,
