If the corruption is due to hardware failure, your data is probably lost. Ditto if the corruption is so bad that fsck_ffs can't handle it. You can e.g. tell fsck_ffs(8) to use a backup superblock, with the -b option. > Does anybody know whether dump/restore can gracefully handle filesystem > corruption, or will it happily back up and restore said damage to the > pristine filesystem? Dump examines the filesystem to see which files need to be backed up. So dumping a corrupted FS will probably not produce the desired results. If it did, we wouldn't need backups. What you could do is use dd(1) with nc(1) to send a copy of the raw device data to another machine, and try if you can pry your data from that.
