I have a question about the amount of data stored on my backup disc


I have AOMEI Standard on my HP laptop running Windows 7. I backed up 147 GB to my backup disc but I noticed that only about 125 GB is stored on the disc. Is that normal?

Thank you


  • You mean the size of the backup file is 125GB?
  • Yes, the size of the backup file is 125GB

    It is compressed. You can explore the image and see that (almost) all the files are present.
    Pagefile.sys (Often many GB) not because it's a non important temp file in a backup.

    See Menu->Settings->tab Compression.
  • Great information JohnnyboyG, thanks!

    I had never heard of Pagefile.sys,

    I just wanted to make sure that I didn't do anything wrong.
