HP XP7 Replication Manager Application Agent CLI User Guide (TK981-96015, May 2014)

Procedure for when the Information Store cannot be mounted
If the data to be restored was obtained by using a VSS backup in Protection Manager version 04-40
or earlier, the Information Stores to be restored must be mounted. If you cannot mount the Information
Store on the server and the server is not Exchange Server 2007, perform the following procedure:
1. Move all data files (*.edb) from the Information Store that could not be mounted to a different
folder.
2. Mount the Information Store.
When the Information Store can be mounted, you can perform restoration for obtaining the
database at the time of backup (executing the drmexgrestore command without the -recovery
option specified) and restoration with roll-forward recovery (executing the drmexgrestore
command with the -recovery option specified).
3. If an Information Store that cannot be mounted still exists after performing the above steps, the
transaction log files (*.log) or checkpoint files (*.chk) of the storage group might be corrupted.
Move the transaction log files (*.log), checkpoint files (*.chk), and the data files (*.edb) of
all Information Stores in the storage group to a different folder. After all the files are moved,
mount all of the Information Stores. In such a case, you can only perform restoration for obtaining
the database at the time of backup (executing the drmexgrestore command without the
-recovery option specified).
In Exchange Server 2007, do not perform the above procedure. If you have performed the procedure
accidentally, dismount the Information Stores, make sure that the transaction log files (*.log) and
checkpoint files (*.chk) of the storage group, and data files (*.edb) for the Information Stores have
been deleted, and then perform the restoration.
Precautions on recovery storage groups and recovery databases
If you are using Exchange Server 2007 as the database management system, do not specify a recovery
storage group when specifying the storage group. If you are using Exchange Server 2010 or Exchange
Server 2013 as the database management system, do not specify a recovery database when specifying
a database.
Precautions when configuring volumes
If you perform restoration to return to the database at the time of backup (restoration by executing
the drmexgrestore command without the -recovery option specified), configure the volumes as
follows:
• Specify the same RAID Manager group name for all volumes that contain data files (*.edb),
transaction log files (*.log), and checkpoint files (*.chk).
Backing up and restoring data between volumes by using VSS
This section explains how to back up and restore data between primary and secondary volumes by
using VSS. The explanations in this section use operation examples for Exchange Server 2007.
