This method of storage is becoming popular in Enterprise solutions for reducing disk backups and minimising virtual machine storage in particular.

Detailed Description

Benefit to Fedora

This will bring an as yet unavailable enterprise tool to Fedora. Storage is becoming the biggest consumer of energy in the datacentre. De-duplication will help bring that power and cost requirement down.

Scope

Attempts have been made to package as an RPM but seem to have stalled.

How To Test

User Experience

De-duplication will be noticeable to target users by greatly reducing the disk space requirements for backups to disk and for virtual machine storage. Greater reductions are seen where many images/backups share a common data set.

Dependencies

Contingency Plan

None necessary - this is a new feature and does not change any current part of Fedora
