Figure 46 Restoration in units of Information Stores (when the backup target is an Exchange database)
In the above example, Information Stores from IS11 to IS14 belong to the storage group SG1. In this
case, you can restore backup data in the following units:
• Restore only IS11 individually
• Restore only IS12 individually
• Restore IS13 and IS14 at the same time (you cannot restore just one)
Notes:
• When restoring backup data in units of Information Stores, you must apply (roll forward) the
transaction log at the time of restoration. For details on precautions relating to executing
commands at restoration, see the description for the drmexgrestore command in the
manual HP StorageWorks P9000 Replication Manager Software CLI Reference Guide.
Using a dynamic disk configuration
• If multiple storage groups are allocated to a file system (drive or mount point directory) of the same
disk group, you must collectively backup or restore these storage groups.
• To back up or restore storage groups individually, allocate them to a file system (drive or mount
point directory) of a different disk group.
• When allocating an Exchange database subject to backup to a file system (drive or mount point
directory), note the following points:
• You cannot allocate the transaction log file (*.log) to a file system (drive or mount point dir-
ectory) of the same disk group to which data files are allocated.
• For online backup, you cannot allocate the data files (*.edb, *.stm) and checkpoint file
(*.chk) to a file system (drive or mount point directory) of the same disk group.
