a Backup Scheduler: automatically runs backup of predefined settings [files, library settings or both] at set time intervals [1 day, 1 week, 1 month].
auto backups are some times risky so it would be best if it will always keep a previous backup.
e.g.
x1 is todays' backup.
the next day [given it's a daily backup] x2 is the freshest copy, but x1 still exist.
the day after that, x3 is the main back up, x2 is the previous backup and x1 is deleted.
this could save a lot of songs when the hard disk hits the fan.
