Not sure if anyone else has noticed this.. Previously the time machine icon in the menu bar would only change to an exclamation mark if there had not been a backup in the last 10 days. I normally backup once every 5 days as my MBP is not for work. The icon now always seems to be notifying that there has been a delay since the last backup. I don't use a time capsule, and instead opt for an external drive. Even though the last thing I did in te evening was backing the drive up, opening my MBP this morning it says that there has been a delay! I can't seem to find a setting to change the time period back to the Snow Leopard definition. Anyone else finding an issue with this? Are Apple trying to make me buy a time capsule for more regular backups?
