Backup taking over 24hrs to complete, file size is twice the size RRS feed

  • Question

  • Reading through other forums, it is not unusual for the backup to take a considerable length of time on the first backup, however I am finding that the first backup is massive compared to the file size that it is backing up. My c: drive is 429GB, however my backup file is 762GB. Why is it so much larger. I am backing up to a 2nd hard drive internally over SATAII so there should be no speed issue.

    I believe I have 3 user accounts...would my computer be backing up a system image for each? If so, any ideas on how to stop it?

  • Hi,


    The backup files include image disk and data files, I suspect you checked all backup options, therefore, the backup files include C drive and your three user’s data files.

    Hope it helps.
