VDP version: 6.1.2.19
Number of backed up VMs: 25
Non-deduplicated size: 6,113.826 GiB
Deduplicated size: 3,128.997 GiB
Dedup ratio: 1.954/1
You might wonder why the compression ratio is so "low":
This certainly is not a very "average" environment. The major portion of storage is occupied by seismological time-series data already compressed by factors between 4:1 and 6:1.
I guess most of the compression happens with the "regular" Linux and Windows VMs in the backup set.
The lesson it should teach you: don't expect miracles if most of your data is already compressed.
For me a compression ration of almost 2:1 is pretty impressive already.
