10 Things You Need to Know Now About Data Deduplication

2 of 11


Avoid managing multiple deduplication repositories by deploying a deduplication solution that will scale a single repository as needed.

Data availability

Make sure your deduplicated data is available: look for disk mirroring and appliance clustering to guarantee immediate availability for fast recovery from a failure.

4 of 11

Integration with backup

Deduplication should be tightly integrated with backup/archiving processes; ideally you should be able to install the deduplication system on the same appliance as your backup application.

5 of 11

Open architecture

The deduplication system should be open and able to run on the server/appliance of your choice; deduplication can be deployed as a storage appliance, gateway appliance or even a software appliance. Choose what fits into your environment and answers your needs.

6 of 11

Ease of implementation

The solution should be easy to implement and non-disruptive to your existing infrastructure.

7 of 11

Evaluate time to recovery

A good deduplication system will not degrade the restore time required for restructuring data.

8 of 11

Total cost of ownership

Remember that the cost of a deduplication system is both material (hardware and software) and management cost; factor in both when evaluating your ROI.

9 of 11

Virtual deployment

Don't forget that deduplication can be deployed on a virtual appliance, saving you hardware cost and allowing you to take full advantage of your virtual infrastructure.

Dedupe ratio

Don't focus on the theoretical dedupe ratio that vendors publish; the ratio is contingent on many factors unique to each deployment.

Inline or post-process?

Choose the solution that gives you the best performance to support your backup window.
