• CPU: 3.0 GHz x 2
• Memory: 4 GB
• Storage system: HP P9500
• If you change settings for the following files, restart the Protection Manager service:
• Application Agent configuration definition file (
init.conf )
• RAID Manager-linkage definition file ( DEFAULT.dat )
• For the storage groups subject to backup and restoration, do not enable circular logs. If a circular
log is enabled, you cannot perform backup and restoration by using VSS.
Restoring backup data obtained using VSS in units of Information Stores
When using Exchange Server 2003 and Exchange Server 2007, you can restore backup data
obtained using VSS in units of Information Stores (in units of
*.edb and *.stm data files). Restoring
backup data in units of Information Stores makes it possible to quickly restore just the required data
files.
To restore backup data in units of Information Stores, you must partition the disk into units of data to
be restored. Therefore, take into account the unit of restoration when allocating data files.
Database configurations that allow restoration in units of Information Stores
• Configurations in which only the Information Store data files (
*.edb
and
*.stm
) to be restored
individually are stored on separate disks
• Configurations in which only Information Store data files ( *.edb and *.stm ) to be restored
individually are stored on the same disk
• Configurations in which multiple Information Store data files within the same storage group
are stored on the same disk
You can perform restoration of all Information Stores stored on the same disk provided that
you specify all the Information Stores. In this case, if you do not specify all Information Stores
stored on the same disk, the command will end with an error.
Database configurations that do not allow restoration in units of Information Stores
• When data files ( *.edb and *.stm ), transaction log files ( *.log ), and check point files
(
*.chk
) in different storage groups are located on the same disk, Information Stores below
a storage group that shares the disk cannot be restored individually.
