I am relatively new to OS X/Apple. I have set Backup 3 to do programmed backups to a Network Attached Storage Drive (IO Gear). The problem is that when the mac mini goes to sleep, it seems to lose the connection to the NAS. Often when I come back a day later, there are several backup jobs waiting to be executed - they won't execute until I open Finder, click on network, and connect again to the NAS. Any suggestions to eliminate the bottleneck?
