There are many ways to backup your personal data to a second drive or elsewhere.
I currently use
FreeFileSync (FFS).
Installing FreeFileSync (FFS):

Download FFS for Linux from:
https://freefilesync.org/download.php
(There are plenty of screenshots and tutorials available there also).
Right click on the
FreeFileSync_13.1_Linux.tar.gz...
