You could try DAR

I just wanted to update on the DAR feature:which netback up supports. File-level DAR is supported; directory-level DAR is not supported.

DAR can be used when restoring files, but not when restoring directories. Backups must have been performed with the NetBackup catalog set to binary mode.For backups made with the catalog set to ASCII mode, restores cannot use DAR, because ASCII mode did not store the required DAR offset information on each backup. Note that all backups made prior to NetBackup 4.5 used ASCII catalog mode.restoring files. IN a single directory if only the files are selected only then DAR will come into scene.

I was wondering the exact same thing. I am using a FAS940c with Netbackup 4.5 MP3. Even if you use ndmpcopy (which by the way is extremely cool for migrating files from filer to filer) it's slow as dirt on phase I. And you are right, there is little to no cpu usageage and disk i/o is low.

Once it gets into the later phases it starts ripping like crazy. I am not sure if this is "working as designed" but I also noticed the restore time is insane. I was dumping 1.4M files as a test, it took 3hrs 13m to complete my backup (131 GB). Now, the really scarry part is, have you tried a restore. To restore 1 file, took me about the same time, I guess it reads the entire dump beginning to end despite the selected files.

Phase I of ndmp (mapping regular files) is running very slowly on my FAS960 with 6.4R1 and Veritas Netbackup 4.5 FP4 I have a volume with around 17M files, and this phase takes 7 hours for an incremental dump! On a vol with 15M files, it takes 4 hours! CPU usage is low, even during backup. Is this a bug in 6.4 or is there something that can be done about this?

Thanks,
