Disk space used per policy/client
Hi! Is there a way to determine how much disk space a policy (or client) uses on a deduplicated disk storage? Info: We use for almost all backup policies SLP's to write the data to the disk stor...

One of the "joys" of deduplication is you never know what you will get, until you do it. The only way to know is to put some data down and see. You can "guesstimate" based on similar data - if you have VM already for example, you can assume additional VM will get the same dedupe. Since my data domain allows me to have 256 separate file systems, I create new targets as much as possible - so each of my oracle DB has its own target, VM and Isilon grouped similarly.
As you can see from my data below - i get a wide variance. averages about 8x for the whole thing.
