With the NFS mount we are seeing 8-14 MB/s transfer rate. I could never get NDMP to work the way I wanted it too -- This is how we ended up with the solution we did. The dump data we get from the netapps (Done nightly) is used only if we have a disaster -- else all other data is either reovered from the tape backups (or from the snapshot data) We keep about 3 weeks worth of snapshots (8 daily, nightly, weekly) -- then rotate it again- so far this has worked pretty nicely now for about a year an a half ---

what sort of backup rate do you get over nfs? to my single DLT7000 Q2.15 i regularly get 4-4.5MB/s (if its not crashed :-P ) backing up two F520's via NDMP.
