Find out what your peers are saying about Dell Technologies, Hewlett Packard Enterprise, NetApp and others in Deduplication Software. Updated: April 2024.
What is deduplication in networking? Deduplication is the process of eliminating duplicate copies of data from a system. Data deduplication improves storage utilization and can be administered in both data backup and network data schemes. Often called single-instance storage or intelligent compression, data deduplication optimizes your data backup storage by ensuring that only one instance of data is copied and stored.
I think the most important features to look for are whether dedupe is online or at rest and if the block size is fixed or not.
You should look at these feature and parameters:
