Check Time Machine's Latest Backup with tmutil

Two tmutil queries answer 'is Time Machine working?' — status shows the running state, latestbackup the newest backup.

Run `tmutil status` for the current state, then `tmutil latestbackup` to print the date-named folder of the most recent backup.

01Command

Command

$ tmutil status && tmutil latestbackup

02What it does

tmutil status reports whether a backup is running, how much has been copied, and whether the destination is available. latestbackup prints the timestamped directory inside Backups.backupdb or the sparsebundle for network destinations; its date is your real 'last backed up' moment. If latestbackup returns nothing, no backup has ever completed to the current destination — a red flag worth checking monthly rather than after a disk dies.
