This article explains core backup strategies, including full, incremental, and differential backups, and shows how recovery needs like RPO and RTO shape the right choice. It also covers enterprise options such as electronic vaulting, remote journaling, remote mirroring, and the 3-2-1 rule for resilient recovery planning. #RPO #RTO #3-2-1
Keypoints
- Full backups copy everything and are simplest to restore.
- Incremental backups are smallest, but restore depends on the full chain.
- Differential backups restore faster because they need only the last full backup and the latest differential.
- Electronic vaulting, remote journaling, and remote mirroring support systems that need rapid recovery.
- The 3-2-1 rule requires three copies, two media types, and one offsite copy.
