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).
My backup strategy:
Data:
- Sycnthing with 1x Copy with my Clients and 1x Copy on my Server accessible via Nextcloud
- Daily Push-Backup with of my Nextcloud-Data-Folder via Kopia to Backblaze
- Daily Pull-Backup of my Nextcloud-Data-Folder via QNAP-NAS in the basement
VM:
- Daily Backup of my VM’s to a Proxmox Backup Server running on QNAP-NAS
- Daily Backup of my VM’s to BackBlaze (but encrypted before)
Still, I’m not fan of having just one Cloud-Backup. So I think I will also get Hetzner Cloud Storage for Borg Backup additional to Kopia.
Goal:
- Different Hardware (Server, QNAP, etc.)
- Different Backup software (Syncthing, Kopia, Borg)
- Different Backup technique (Push, Pull, Snapshots)
- Different Locations
How do you prevent your backups from file corruptions being backed up?
Versioning is helping, I can go one year back in history.
