on the topic of backups
people are always looking for backup solutions. and what these people need to understand is that a backup is a 2nd (or 3rd or 4th) copy of something. moving your files to a server and deleting them from your machine is not a backup. that is moving your files to another location. when your server goes down, you still have no backup.
in other words, make copies to your server, but don’t rely on that. computers break all the time. local machines as well as servers.
