the production system (the Remote Copy primary system), the synchronous mode backup system, and the asynchronous periodic mode backup system.
Setting Up Remote Copy Volume Groups for Storage Groups
1.Identify the virtual volumes that contain the storage group and log files to be copied.
2.Create one (and only one) primary Remote Copy volume group per mailbox database.
3.Add the virtual volumes belonging to the storage group files and log files to the primary Remote Copy volume group, and add the associated secondary virtual volumes to the secondary volume group on the backup server.
CAUTION: The relationship between storage groups and Remote Copy volume groups is 1:1.
•You must add storage group files to a primary Remote Copy volume group for Remote Copy to function.
•You must add files from only one storage group to one primary volume group.
◦Do not disperse files from one storage group over multiple primary Remote Copy volume groups.
◦Do not add files from multiple storage groups to the same Remote Copy volume group.
If you do not ensure your system meets these requirements, you run the risk of data corruption and loss.
4.Synchronize the Remote Copy primary and secondary volume groups.
Recovering a Storage Group from a Remote Copy Backup Server
If a storage group crashes at the site that holds the production system (the Remote Copy primary system), you can recover the data from the backup server at the remote site as long as it is set up in an identical manner to the original production server.
NOTE: If you are performing a promote restore for volumes in a Synchronous Long Distance Remote Copy relationship, you must manually stop Remote Copy before initiating the volume promote restore.
1.On the backup server, use Recovery Manager to mount the virtual copy to the production server.
2.Log onto the production server and stop the Exchange instance and its dependent services.
3.From the mounted virtual copy, manually copy all necessary storage group and log files to the corresponding storage group location.
4.Restart the Exchange instance and its dependent services.
5.Log back onto the backup server and unmount the virtual copy.
