Restore Exchange DAG

Below are the steps for restoring data into an Exchange DAG.

Pre-restoration Requirements

Refer to the following instructions to restore your Exchange database in Database Availability Group (DAG).

The database restoration is required to restore on the active database only. You can identify the Exchange server with the active database from the Exchange Management Shell.

Type the following command in the Exchange Management Shell.

Get-MailboxDatabase | ft name, server 

It will show which Exchange server is hosting the active mailbox database, i.e. Mailbox Database 01 and 03 are hosted on EX1, while Mailbox Database 02 and 04 are hosted on EX2.

[PS] C:\>Get-MailboxDatabase | ft name, server
Name                   Server
----                   ----
Mailbox Database 02    EX2
Mailbox Database 01    EX1
Mailbox Database 03    EX1
Mailbox Database 04    EX2

When you can identify which Exchange server is hosting the active database, you can logon to that Exchange server to restore the database.
