Does anyone know of a command line method to select the active Time Machine disk? I would like to alternate between two backup disks for redundancy. I would like this to be automated, presumably via cron, perhaps launchd.
There is an AppleScript method to swap disks, but I am doing remote system administration and cannot rely on GUI scripting. I would presume there is sufficient control of Time Machine using the defaults command, but am not sure how to achieve this yet.
