Our Management told us we needed to wipe down some our drives, who knows why. We were told to delete certain documents and then backup the remaining files to a external medium, wipe then restore the remaining files.
I usually just use Dump/Restore to do backups as it works great and is very simple. I simply used rm() to delete the files, created a zeroed file to fill the drive, deleted that file, then did a level 0 dump to a external medium, did a secure-erase via the drives firmware and now am restoring.
Though I have to ask, since dump works with the inodes and filesystem, will there be a trace of the deleted files in the dump of the drive, possible any metadata or links left over? This seemed pretty important to management, so I don't want to let them down because of my archaic backup habits.
