"Dedupe" and "Compression" meaning in reports

Veeam Logoby marius roma » Wed Apr 13, 2016 2:12 pm

In the header of each backup report I see a field "Dedupe" over a field "Compression".
My backup job is configured as Incremental, with the "Enable inline data deduplication..." check box disabled and the "Compression level" set as "Dedupe-friendly".
The targe NAS is able to perfomr deduplication.
In the "Dedupe" field of my reports I read values like 5.5x or 12.3x: what do they mean?

Deduplication value is calculated as the backup file size in relation to the total data size, so considering that swap file blocks are still excluded and VM is pretty static, I'd expect positive dedupe rate values.

Thank you for the clarification.
So, can I say that the value have nothing to se to the deduplication of data being transferred to the NAS?
Where are all this information documented?

This value has nothing in common with the storage device deduplication ratio, if this is what you mean.
