In some circumstances, the backup disk is full, but Time Machine cannot delete enough old files to make space for new ones and it just stops. If you keep your eye on Time Machine status, you may spot it deleting old files. When the drive is full, the oldest versions will be removed, leaving the most recent one. If you edit a file every day, then a new version is stored every day. When the disk is full, Time Machine should automatically delete the oldest versions of files.
