Why did backing up to Time Machine become super slow?
Trying to backup to my external HD. I'm using Snow Leopard, and this isn't the first back up. Had computer for 2 years, and this just started about a month ago. No new updates around that time that I can recall. Backups taking more than 24 hours! I used to be able to have a backup in less than an hour, so I had hourly backups. Any idea how to fix this? I don't want to neglect backing up and need them, because I've had to use them before in the past.
MacBook, Mac OS X (10.6.8)
