This is what I've been doing for the past couple years:
1. Pictures are either manually copied to a staging folder on my storage server (for DSLRs) or automatically synced there via Syncthing (for smartphone cameras). For the latter, Syncthing is set up to preserve deleted files in case of accidental deletion.
2. The storage server runs zfs and takes 10-minutely snapshots of all datasets, which are replicated to 2 servers using zrepl: one sitting upstairs and another I rent from Hetzner halfway across the world. Replicated snapshots are kept for 2 years. Everything uses zfs' native encryption, but the replication targets do not have the key.
3. For the really important pictures and other documents, I create 2 additional backups: an encrypted backup to Backblaze B2 via rclone and burning them to M-DISC blu-rays. This is sort of a last ditch thing in case a zfs bug renders the primary backups unreadable.
