• 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 2007, you can restore backup data obtained by using VSS in units of
Information Stores (
*.edb 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 ) to be individually restored
are each stored on a separate disk
• Configurations in which only the Information Store data files ( *.edb ) to be individually restored
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
