Recover deleted files in Oes 11 NSS

What options do you have to recover accidentally deleted files in Oes 11 NSS? Salvage did not work. With google you can find many different tools, e.g. Stellar Phoenix Novell Data Recovery (NSS), but does anybody have any real experience on how to do that or what are best available tools? NSS disk is ok and there's nothing broken there, just accidental delete without backup.

    No experience with file systems level data recovery. I know some of this is only useful if you also have a time machine, but NSS has that "built in" if you enable salvage, and if you keep > 10% of the pool free. And there there is having a tested recovery mechanism... that would be helpful. But the key features of a tool I would use would be non-destructive recovery, it should not be writing to the disk. Before using any tool, get a proper backup / recovery system in place so that if the data recovery tool eats your disks, you can get the rest of your data back. In instances like this, if you can't gurantee that the bit-twiddling utility won't (further) corrupt your disk, I'd go to the effort of making a disk image of the disk holding the pool.
