Sam, I came across that particular issue in the past. If you are using the GUI to perform your file-level NDMP restore then that's your problem!!!
If you want to have restore performance similar to that of your backup then perform the restore via the CLI. It'll be a LOT faster. You may create virtualfsmap using the appropriate paths as destination then perform the restore operation. Good luck.

Backup is very fast and appears to work very well. Restore of and individual file is a different story altogether. We restored one 90MB file out of a backup of a 120GB volume with no differentials. The restore took about 30 minutes. I'm trying to figure out why such poor performance on file level restore. My initial assumption is that since the backup is at the block level and the NAS file system is write-anywhere, the blocks for an individual file could be scattered all over the tape (TS1120). Anyone have any experience/suggestions with file-level NDMP restore? Thanks Sam Sheppard San Diego Data Processing Corp. (858)-581-9668 IMPORTANT: E-mail sent through the Internet is not secure.
