A few question on dedupe:
1) What is the client requirement to use client-side dedupe? e.g. can a client w/ 2GB RAM do client-side dedupe? Do I need to set anything on the Remote Agent on the client?
2) I ran the same full backup to dedupe storage job two times in a roll. It is a files backup job. The 1st job took 11 min and 2nd job took 18 min. Isn't that dedupe supposed to copy the changed block only? I would expect the 2nd job complete very quickly but it is not? Am I mis-understanding the concept here? (but differential job seems very quick sometimes)
3) Should I enable Advanced Open File for dedupe backup jobs? For File/SQL/Exchange? Will it affect performance?
I'm new to this dedupe thing and trying to understand more.
Thanks all.
Joseph.

Hi Mus Seth,
Thank you for your time to answer my questions in details.
So in short, can I say: deduplication will save storage space, but not necessary faster??
Thanks!

Yes...the more you run your dedupe job and retain data for longer, the better the dedupe ratio and disk utilisation. Dedupe is about that, not about performance for the most part.
Thanks!
