I have a Mac OS X Server and seem to be the only one in the world who is using one...<br><br>It is a Mac GUI with Unix underneath and the ability to drop to a command prompt if required. Unfortunately I have very minor skills in Linux and no actual Unix.<br><br>Problem: Two consecutive Mondays, most recently at 3:16am when no one was in and the backup job was not running, all files starting with a hash symbol were deleted. This affected several thousand mission critical files.<br><br>Question: What deleted them, how do I check for it and how do I stop it happening again?
