Time Machine Backup Larger Than Hard Drive
I'm trying to run a time machine backup. According to time machine the backup is OVER 1tb but my hard drive is only 1tb. Also, only about 650gb are in use. It's taking 8-10 hours to complete backup.
See screen shot of comparison of hard drive use and time machine preference windows.
Why is this happening? How do I stop it from happening?
Thank you!
