Duplication of dedup folders between 2 servers

Hello,

I want to use optimized deduplication between 2 servers.

In the documentation I just read:

"For client-side deduplication and Backup Exec server-side deduplication, you must configure one deduplication disk storage on the Backup Exec server from which you want to copy the deduplicated data. You must also configure one deduplication disk storage on the Backup Exec server to which you want to copy the deduplicated data."

So I have Server A and Server B.

My question is : is the dedup disk storage on the server (named "Server B") I want to copy the deduplicated data can be used by "Server B" himself for his own backups ? Or this dedup disk storage must be dedicated only for replicas backup of Server A ?

Thanks in advance
