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).

Aren't you scared about loosing your data?

No. I still have files from 1991. I've got files that have migrated from floppy disk to hard drive to QIC-80 tape to PD (Phase Change) optical disk to CD-RW to DVD+RW and now back to hard drives.

What if I get a ransomwarei don't realize and all my backups get encrypted too?

Then you need to detect the ransomware before you backup. I use rsync --dry-run and look at what WOULD change before I run it for real. If I see thousands of files change that I did not expect then I would not run the backup and investigate what changed before running the rsync command for real.

Or if the backups are corrupted

I have 3 copies of my data. Local file server, local backup, remote file server.

I also run rsnapshot on /home every hour to another drive in the machine. I also run snapraid sync to dual parity drives in the system once a day.

I generate and compare stored file checksums twice a year across all 3 copies to detect any corruption. Over 300TB I have about 1 failed checksum every 2 years.

and my disks breaks?

If one of my disks breaks I buy a new one and restore from backups.

But also I'm afraid about cloud

I don't use any cloud services because I don't trust them.

About rsync --dry-run, let's say I got a ransonware but its till encrypting the data will it detect the changes?
