I use SyncToy, a free Microsoft program. My Documents, Pictures, Music and Videos folders are echoed to 2 external hard drives. I use task scheduler to run SyncToy every night. Evey night any changes to my folders are echoed to the folders on the hard drives. I have made the drive letters of the 2 drives Y and Z. By alternating the 2 drives every week I can maintain an off site backup that is only a week old and a backup that is current every night. I save the exe files for each program I install and the corresponding activation code in a folder for each program. These folders are kept in a folder called Downloaded Programs. I never backup the operating system. Windows 10 is always available on Microsoft's web site as a free download and is free to install on any computer that has had windows 10 installed in the past.
