Yes there is. You can copy files to another disk. Third time I've said that.
you don't need an app for that.
It's also the simplest solution that fits in the head space of a user.
Linux doesn't come with a backup app either. You have some tools (dump/tar/dd) from which you can build one or you buy one in (bacula, Amanda etc). Same with windows (powershell, vhd cmdlets etc).
