Lots of archive warnings during server boot

[Andries1985]

I'm getting an archive message warning for every backup in the ./backups/automatic directory when starting up the server. This takes a while when you have tons of saves.

The warning messages (this is just a small part) in the console is as follows:

[16:24:30 WRN] Failed to create hourly archive <s:Server.Saves.AutoArchive>

Would be nice if it wouldn't create a message per save but just one time.
