For now my server doesn’t have very important data most of it are your “Linux isos” I can just download again and I’m thinking of starting to move my file and photos to the server but in afraid. What if I get a ransomwarei don’t realize and all my backups get encrypted too? Or if the backups are corrupted and my disks breaks? But also I’m afraid about cloud because I’ve seen some posts about people getting their google accounts closed without notice for breaking TOS (maybe they did something wrong maybe not).
Personally my NAS isn’t my main storage. I still use Google Photos and Google Drive for my important stuff, I just need to configure Rclone to download my stuff on it.
The one thing I’m really self hosting only is my music, outside of the couple of CDs and downloading from iTunes, I don’t have a proper backup.
