It depends what is your business requirement. Practically one copy is enough, if you have regular backup running. Focus on <br />
<br />
Redundancy: DB Copy, Server, Power Supply, SAN<br />
Resiliency: Server and Site<br />
Recovery: Backup strategy.

I currently have 2 servers in the DAG A and B, and will be adding 2 more Mailbox servers to the DAG, C and D<br />
My question is right now the dbs that are on the 2 servers in the DAG (A and B) have copies of each of their DBS on each. Now I will be adding 2 more MB servers to the DAG,(C and D) but these 2 will have different dbs than are on the other 2. Is it ok to have copies of dbs on the original 2 MB servers A and B between them and then have the copies of the DBS from the 2 new MB servers C and D between them?<br />
So basically A and B share copies and C and D share copies...
