Of course having a backup is a good idea. If things go wrong, they can be fixed. But like G_Yoshi said, it should be on the manager's computer. I mean really, who uploads something and then doesn't have a copy of it for themselves in case something happens to it? It's a computer. Things will go wrong. You have different people working on the server uploading things you say? Then download things as they change.
Heck, the best thing would be to have one copy uploaded, one on the manager's harddrive, and two copies burned to CD, with one of those copies put in a safe place where the CD can't get ruined, just in case.

But yes. It's the manager's responsibility. Not Graal's.
