Small enterprise backup choices range from traditional disk to tape (D2T) to continuous data protection (CDP). Three decisions guide backup strategy selection for each application:
- Describe backup objectives including restore-time objectives, restore-point objectives, off-site suitability, and business value.
- Define backup architectures, such as disk-to-tape (D2T) or disk-based online (DBO), to meet backup objectives.
- Determine backup methods including snapshots, synchronous mirroring, and incremental cloning.
To achieve backup objectives, introduce disk into the backup equation. Also, leverage branch office locations for increased service interruption resistance and resilience.
