exchange Veeam agent and deduplication
We have 3 Exchange servers with 3 replicas of an database on each server.
I put all three physical servers in the same Protection Group and make one backup job from the group.
Is the job then using deduplication, so the 3 databases only take up repository space for 1?

Re: exchange Veeam agent and deduplication
Hi Brian - For Veeam Agent for Windows (which does the backup), there is a built-in storage efficiency engine. Primarily it is compression, and it is explained here: https://helpcenter.veeam.com/docs/agent ... tml?ver=21

Re: exchange Veeam agent and deduplication
Hi Brian.
Deduplication works on job level. If you have managed by backup server job type with cluster type for agents, then all hosts are going to be processed by single 'backup task' and you will see good deduplication ratio as data will be deuplicated between multiple source hosts (cluster nodes). However, if you run regular jobs (server or workstation type), then each agent will have it's own backup task, so deduplication will affect only the data blocks within single machine, thus you will see very minor deduplication ratio.

Re: exchange Veeam agent and deduplication
If I make a Protection Group and put five Exchange servers (physical) in that group. Then make a backup job from that Projection Group, and chose Type: Server and “Mode Managed by backup server”.
Does it then dedub. alle 5 servers in that job?

Brian,
Only in case these exchange servers are nodes of singe Exchange cluster and you are backing them up via failover cluster job type. Cheers!
