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).
Immutability! For some reason nobody here mentioned this! There’s only one thing which can protect you against ransomware - backup storage with immutability! It can be S3, custom script setting immutable flag, read-only snapshots and so on…
But… You need to make sure, that your backup storage is properly tightened, so even you, as the owner, cannot change immutable data without physical access to the server.
didn’t know this could be done, I will check it for my photo backup as they are not gonna change. Thanks
