The Business of Deduplication

We all recognize that deduplication is a potentially game-changing technology. By cutting the amount of capacity your backups require, it can make VTL backup as cost-effective as tape.

However, be sure that you implement a solution that actually solves your business issues—meeting SLAs, backing up within your backup window, restoring data efficiently, reducing labor cost, and simplifying complexity -- without creating a new one.

For example, controlling capacity growth by slowing down your backup process is just moving the problem around. That is, if your deduplication technology may not be a sound choice if it jeopardizes your backup window or prevents you from restoring data quickly.

You may have to use multiple deduplication systems to backup and deduplicate your data within your backup windows. Now, you have multiple “silos of storage” to manage.

That adds complexity, labor cost, and greater potential for human error. It’s also an inherently less efficient deduplication methodology since data is never deduplicated across multiple systems.

Remember that to keep your data protected; you need to back it up to the protection of your VTL as quickly as possible. If your deduplication technology is slowing that process or adding complexity to your environment, it is adding risk instead of reducing it.
