    Hi all,

    Could anyone please tell me if commvault incorporates Fixed length deduplication or variable length deduplication? Also, if Variable length deduplication, then How does it work ?

    From my understanding Commvault Deduplication is a block level deduplication (Fixed length), if the blocks of the first file never been backed up before, and it gets deleted, the blocks of second exact file will be backed up again.

    However when configuring the Deduplication Policy you can change the length at the policy level from 128k (Default) to 512k (which is the suited size for Cloud writes.
