I know i can get the time stamp of the latest Time Machine backup with the command
tmutil latestbackup | grep -E -o "[0-9\-]+$" but this only works when my backup disk is plugged in. If not, i get the error message Unable to locate machine directory for host.
Is there any other way to figure out (through scripting) when the last backup was made?
I'm running OS X Mavericks and the use case would be to eventually run this as remote monitoring for Macs, say, using collectd.
