That error might depend on what program you use to make the backup and to what medium you backup. After all, uploading a file to Dropbox with Chrome is quite something else as burning a folder to CD with Nero.
Does that CD say it's compatible with Windows 10 and does your hardware meet the minimum sysrtem requirements?
