Backup is smaller than original

My backup is smaller than the original and has fewer files. Why?

A default backup profile will not copy the following:

  • SBSE____.*
  • desktop.ini files
  • hiberfil.sys (the Windows hibernation file)
  • pagefile.sys (the Windows memory paging file)
  • PGPWDE01
  • Recycle bin folder
  • System Volume Information folder
  • thumbs.db files
  • \Windows\Temp\ folder
  • Junction points are not followed

This may result in fewer backup files and hence a smaller backup size. You can also choose to filter out files that Windows itself states should not be copied.
