You can see that the ‘expired’ backups are one 1 and 2 months old May 16 10:42:05 com.apple.backupd[1014]: Starting automatic backup May 16 10:42:14 com.apple.backupd[1014]: Backing up to /dev/disk2s2: /Volumes/Time Machine Drive/Backups.backupdb May 16 10:42:38 com.apple.backupd[1014]: Will copy (41.6 MB) from Macintosh HD May 16 10:42:38 com.apple.backupd[1014]: Found 318 files (41.6 MB) needing backup May 16 10:42:38 com.apple.backupd[1014]: 4.93 GB required (including padding), 2.82 TB available May 16 10:45:41 com.apple.backupd[1014]: Copied 477 items (41.4 MB) from volume Macintosh HD.
