Data De-Duplication Versions
| Requirements | De-Dupe Policy | How it works |
- Short to medium backup window |
Adaptive De-Duplication |
- Segments land in disk buffer, then de dupe during ingest - Replicate changed blocks immediately - Behaves like conventional in line at midrange speeds - Adapts to faster ingest speeds to avoid throttling the backup job - Reads made from cache as space is available for faster reads/tape creation |
| - Short backup window critical - Need to retain data on disk - Want to maximise performance - Can defer replication |
Deferred De-Duplication |
- All data written to disk during backup window - De-duplication replication occur in fully deferred post process outside window - Reads from cache as space available for faster read/tape creation |
| - Shortest possible backup and restore windows - When data does not de-duplicate - When data is not retained - For non-backup archive applications |
Native VTL/NAS |
- All data brought directly onto disk at highest speed - Uses conventional VTL and NAS presentations - Hardware compression in streaming mode provides capacity and performance advantages - Conventional NAS mode provides conventional storage and archive storage |
