4.7 Configuring Recovery Manager for DAG
Recovery Manager for Exchange provides support for Database Availability Groups (DAG)
(4.1.0 and later). DAG configurations can be implemented at a single site or span multiple sites.
Each configuration will have one central Recovery Manager for Exchange backup server and at
least one active Mailbox Server and a potential maximum of 15 passive Mailbox Servers. For
example:
■ If your DAG configuration uses a single InServ at a single site, you will require one Backup
Server.
■ If your DAG configuration spans multiple InServs at a single site, you will require one
Backup Server.
■ If your DAG configuration spans multiple InServs at a single site, you will require an
additional host server for verifying mailbox virtual copies.
■ If your DAG configuration spans multiple InServs at a single site, you will need to connect
one InServ to the backup server and the otjher InServs should have additional hosts
connected for virtual copy verification purposes, unless the production DAG host is used as
verification server.
■ If your DAG configuration spans multiple InServs at multiple sites, you will require one
Backup Server per site.
You will need to configure the provider to use the InServ that each backup server and
Exchange production will connect to. This is done through the Provider's
ProvCfg.exe utility
(see the Provider's user's guide for details).
■ If your DAG configuration has one InServ, then add only that one InServ using
ProvCfg.exe.
■ If your DAG configuration has two InServs at one site, you will need to add both InServs to
your backup server.
NOTE: The minimum number of virtual copies allowed is 1 and the maximum is
500. The default is 10.
