Only one scheduled backup, but 2 occurr

[rukiddin]

I currently have a backup scheduled every night at 11:30, I use growl to send me an e-mail notification.

however, each night 2 backups occurr, one is successful, the other fails to find the destination drive and I get a failure e-mail. I cannot figure out how to remove the second backup attempt when I only see one in the scheduled backup list.

has anyone else experienced phantom backups?

Also, it seems like SuperDuper! doesn't quit like it should every time. It should quit after each backup, but sometimes I need to go in and quit manually. Often times this requires a FORCE quit. Any suggestions?

Thanks

Mike
