Good on you to protect sensitive data such as others' pictures. I always hope that people do this if I send them something.
I have a couple of external storage devices (ESD) all of which are encrypted using VeraCrypt. Sadly one of them got corrupted about a month ago, causing me to lose over 3 TB of files. I hope I'll be able to restore the data at some point, but it seems to be a hardware issue. Anyway, that ESD stored games, movies, music, manga, software, 2FA backup keys, and several encrypted file containers with loads of private nsfw pictures of other people, and of me. I can rebuild anything entertainment related over time, but not the pictures. :c
The other ESD's house backups of all my devices. But sometimes I think, what's the point of keeping everything when I don't really need those back-ups. The history they hold is lost on me. I changed too much and feel mostly sad when I look at old pictures, and browse old documents.
