Incremental vs Deduplication
Hi all,
Just want to seek for your thoughts or knowledge regarding Incremental vs Deduplication, since I thought this 2 subjects are like the same.
Thank you and best regards!
They are not the same.
Deduplication is a technology to reduce the space consumption made by backup data for both full and incremental backups. Different vendors got their own dedupe engine. Veritas got their MSDP pool, Dell EMC got their Data Domain. Both has pro & cons.

Incremental is a schedule definition of what data that should be protected. Data from a incremental backup may be send to a dedupe pools, just like the data from a incremental may end on tape.

Hope this helps :-)
Hello,
another point for comparison : while increments are related to a certain client and type of data, deduplication is global across many different clients.
