SwitchBack supports the required AppleEvent suite, and is fully AppleScript-aware. You can use AppleScript to execute a series of backups automatically. Programs that permit scheduled execution of scripts could permit you to do a daily backup, and then shut the machine off. This ability is very powerful.
The following script launches SwitchBack (if it is not already running), brings it to the front and opens four backup documents in sequence. These documents should be set to start automatically. Once completed, SwitchBack is told to quit. The final command sends a “Shut Down” event to the Finder to turn the machine off.
tell application "SwitchBack 2.2"
activate
open alias "Flying Disc:Backups:Data"
open alias "Flying Disc:Backups:Development 1"
open alias "Flying Disc:Backups:Development 2"
open alias "Flying Disc:Backups:Libraries"
quit
end tell
tell application "Finder" to «event FNDRshut»
If the SwitchBack documents required volumes to be mounted and unmounted you should set SwitchBack’s preference After Auto-Start to Do Nothing. In this way SwitchBack will remain the frontmost application for each document opened.
