Thank you for your comment. DeltaStor understands the objects contained within each backup set by looking at the metadata embedded within the backup data stream. This happens transparently to the user and allows us to more effectively find redundancies.

Encryption randomizes the source data. This makes deduplication difficult if not impossible because there are no consistent redundancies. This situation impacts all deduplication algorithms, and your best bet is to disable encryption, if possible.

I am new to deduplication but I heard from someone that the Delta Store product is superior to other deduplication because it knows and can understand what is in the backup set (and it can therefore do a better job of deduplication).

I am wondering how this happens, do you have some API’s by which you can read the backup catalog or something. Second, I use encryption on my backup. Will Delta Store work with that.

Thanks,

Claire

It is my policy not to comment on unannounced products here on the blog. Deduplicated reduplication is an important feature and I ask that you stay tuned for more details.

I know; I’m playing a broken record. I’m consistent, though. I give DD a hard time for not having global (multi-node) dedupe. I give EMC & Quantum a hard time for their restore speed issue. And I’m giving you a hard time for not having deduped replication.
