You maybe more harder on yourself than needs to be.

most people unless theyre new to computers,, knows that backing files up is much a good idea an do it frequently enough that little to no keepsakes are lost.

my brother had to reformat a previous computer of mine an felt super bad about it cuz he thought i lost all my pictures. but i had just recently backed up my stuff. i still lost some pictures,, but i was just happy to have my computer back up an running an still have almost all my pictures than verses the alternative of nothing.
