I would like to set up an automated backup of my large itunes folder. It resides on an external drive and is excluded from my Time Machine (would overwhelm the backup disk). I have a separate external drive to use as a backup. Is there a simple way to set this up? I've tried SyncTwoFolders, but it didn't seem to run the scheduled backups properly. I came back after a few days and didn't see a backup log. I am now running arRsync, which works nicely but I can't figure out how to schedule it. I am not interested in cloud backup, just local redundancy.
