Seems like any time I back up, like just a few minutes ago, I later get an alert when I click on the TM icon that my last backup was delayed or incomplete. However, I almost never abort a backup. I have my TM backups on an external 1T drive and, when I plug in and start the drive, TM will automatically start backing up. The backup completed a few minutes ago was about 2.13 gigs of files and the progress window indicated that the backup was completed. I don't think I have TM scheduled to backup at specific times, only when I plug in the external drive. What's the problem?? Thanks.
