DP9 - Deduplicated store is way too big

Hi everyone,

we are using DP9.00 with a deduplicated store (stored on an another server).

On the gateway we can see that 1TB of data is used for a 16,5 deduplicated ratio.

When i do a "storeoncesoftware --list_stores" on the server, i've the same informations.

BUT, the size of the "StoreOnceLibrary" is 3.2TB ...

What can i do ? How can i "purge" this database ?

Any advices would be welcome ;)
