The first step in defining your NetVault SmartDisk Deployment Strategy is determining which data to deduplicate. Not all data benefits from deduplication; therefore, it is important to determine which data is targeted to use the NetVault SmartDisk Deduplication Option to reduce its storage footprint.

While data deduplication reduces storage costs by reducing the storage footprint, there is a cost incurred during the restore processes. During the restoration of a deduplicated backup, NetVault SmartDisk has to reassemble the Chunks as it restores the data. This reassembly process, also referred to as rehydration, lengthens the time to restore the data. Therefore, if the Recovery Time Objective (RTO) is important for a specific database, email, or file system, consider the trade-off between reducing storage costs and increasing RTO when you identify which data to deduplicate.
Data that does not deduplicate well and should not be deduplicated includes:
