Primary Product Application
Peer DRS employs a form of log shipping which is the process of automating the backup of databases and transaction log files on a primary server, and then restoring them onto a target standby server. The key feature of log shipping is that it will automatically backup transaction logs throughout the day (for whatever interval you specify) and automatically restore them on a standby server located anywhere in the world. This in effect keeps the two Databases in "synch". 

Installation

Peer DRS is delivered/downloaded as a full installation program. To run, simply double-click on the executable in the Explorer window, or choose "Run" from the Start Menu and then select the application and a wizard will walk you through the installation.

Peer DRS can be configured in numerous ways based on your needs and your environment. It is recommended that you perform a site survey to assist you with picking an initial configuration before installing the software. Below are the two most common configurations along with their requirements


Configuration

Installation on Target Exchange Server

Peer DRS is installed on the same server as the Target Exchange server and the target server has two configured local drives, C: and D: This example has the shared backup folder located on a local drive on the target, but you could also use a network share located on a different machine or on the Primary Exchange server, or some other NAS device. In any case the domain user account that Peer DRS is run under must have read-write access to the shared backup folder.


Requirements:
  • Domain user account PeerDRS must have domain Backup Operator and Full Exchange Administrator privileges
  • Domain user account PeerDRS must have read-write access to local paths, C:\Program Files\Exchangesrv\mdbdata, D:\PeerDRS\Backup\ExchangeA, C:\DRS\LogReplay
  • ExchangeB must have TCP/IP access to ExchangeA and be on the same domain.
  • MS Exchange Server must be installed on ExchangeB with storage group SG1 and database Mailbox Store 1 configured and dismounted.
  • The account that the target Exchange information store process is running under (default is local system account) must have access to C:\DRS\LogReplay.
  • If you want to utilize continuous, real-time replication then the PeerDRS user account must have read-write access to administrative network share: \\ExchangeA\C$\Program Files\Exchangesrv\mdbdata. This usually required granting domain level Administrator rights to this user.

 

Remote Centralized Installation

Peer DRS is installed on a separate server from the primary and the target Exchange server's name is BackupSrv. This shared backup folder is located on the BackupSrv host on local drive D:\PeerDRS\Backup\ExchangeA. The target File Copy Destination folder is the same and the Backup Folder and therefore no extra file copies will occur. The main difference in this configuration is that administrative shares on the target must be configured and accessible by the domain account that Peer DRS is running under.


Requirements:
  • Domain user account PeerDRS must have domain Backup Operator and Full Exchange Administrator privileges.
  • Domain user account PeerDRS must have read-write access to local path D:\PeerDRS\Backup\ExchangeA
  • Domain user account PeerDRS must have read-write access to administrative network shares: \\ExchangeB\C$\Program Files\Exchangesrv\mdbdata, and \\ExchangeB\C$\DRS\LogReplay. This usually required granting domain level Administrator writes to this user.
  • BackupSrv must have TCP/IP access to ExchangeA & ExchangeB and be on the same domain.
  • MS Exchange Server must be installed on ExchangeB with storage group SG1 and database Mailbox Store 1 configured and dismounted.
  • The account that the target Exchange information store process is running under (default is local system account) must have access to C:\DRS\LogReplay.
  • If you want to utilize continuous, real-time replication then the PeerDRS user account must have read-write access to administrative network share: \\ExchangeA\C$\Program Files\Exchangesrv\mdbdata. This usually required granting domain level Administrator writes to this user.

The most important thing to keep in mind is that the account that any of the configured primary and target database instances are run under must have permission to read and write from the drive (usually a network share) where the backup or copied target files are located. Please see the Security Model & Permissions section for more information on security and permission requirements.
