Backup vs. Replication
Backup | Replication |
---|---|
Prevent Data Loss | Swift Recovery in Disaster |
Snapshot in time | Up to date instance |
Cheap, slow storage | Nearly identical storage |
Many Copies over time | 1-3 instances, up to date |
Recovery from any time | Only up to date instance |
Safe from user error | May also be affected by users |
DR is tested regularly | Replication is kept up to date |
