How can I customize the schedule at which Time Machine performs its backups?
I am annoyed by looking at the number of times I see the Time Machine backing up several MBs every hour and then the cleanup.
Schedule backup for every 4 hours ( 4*60*60 = 14400 )
Default is 1 hour ( Rollback procedure )
I would recommend using the app TimeMachineScheduler for this, it provides an easy-to-use graphical interface, and has a lot more features than a simple Terminal-line.
Unlike typing a command into Terminal.app where a typo can potentially create problem, using a graphical user interface is safer.
