Synology has Snapshot Replication and Hyper Backup, what's the difference?

Snapshots protect against 'oops' on shares living on the same NAS, and can't replace real off-site backup. Hyper Backup truly copies to elsewhere. You need both: snapshots for fast rollback, Hyper Backup for 3-2-1 and disaster protection.

Try this first

1. 1Snapshot Replication takes point-in-time snapshots on Btrfs shares. Near-zero space, near-instant. Great for user-error rollback up to 30-60 days back.
2. 2Snapshots live on the same NAS. On hardware failure, fire or ransomware against the NAS, they're gone too. Snapshots aren't backup unless replicated.
3. 3Hyper Backup is a true backup tool: copies to a 2nd Synology, USB disk, Backblaze B2, Synology C2 or WebDAV. That's your 3-2-1.
4. 4Configure both: snapshots for file shares with 30-60 day retention, Hyper Backup off-site every night. Snapshots catch most user errors without touching Hyper Backup.
5. 5For immutability: Hyper Backup to B2/C2 with Object Lock, or to a Synology with WORM folders. Snapshots themselves aren't immutable when the NAS admin is compromised.
6. 6Test restore from both: a user-restore via snapshot, and a full-share restore from Hyper Backup. Only then is your coverage complete.
