Extension Files subject to backup Database subject to backup
*.chk Checkpoint files
In Application Agent, data is backed up and restored in physical volumes units so the object
configuration of an Exchange database requires the following:
• The files to be backed up must all be placed on a RAID volume defined as a pair.
• Deploy the storage group or Information Store by taking into consideration that the unit for backup
is physical volumes.
In Exchange Server 2007:
• If you deploy multiple storage groups in the same physical volume, you need to back up or
restore these storage groups as one group. When backing up or restoring a storage group
separately, deploy the storage group on a separate physical volume.
In Exchange Server 2010 or Exchange Server 2013:
• If you deploy multiple Information Stores on the same physical volume, you need to back up
or restore these Information Stores as one group. When backing up or restoring an Information
Store separately, deploy the Information Store on a separate physical volume.
• When you place an Exchange database that is subject to backup on the volume, note the following:
In Exchange Server 2007:
• You cannot put the transaction log file (
*.log ) on a volume where a data file is placed.
• You cannot put data files ( *.edb ) and checkpoint files ( *.chk ) on the same volume.
In Exchange Server 2010 or Exchange Server 2013:
• When you back up a database, you cannot put the transaction log file (
*.log ) on the same
volume that holds a data file ( *.edb ). Data is restored in physical volumes units so you will
not be able to perform a roll-forward restore operation if you put both the transaction log file
and the database file on the same physical volume. You must therefore put the transaction log
file and the database file on different physical volumes.
• When you set a name for a storage group or Information Store, note the following:
• Maximum length: 64 characters
• Characters that cannot be used
= ; \ / ,
• The operations shown below change information pertaining to the Exchange Server on the Active
Directory, so if you perform any of these operations you will no longer be able to restore backup
data obtained before these operations (that is, you will no longer be able to use the
drmex-
grestore or EX_DRM_EXG_RESTORE command):
• Modification of the paths of the Information Store, log, and system files.
• Addition or deletion of storage groups.
• Modification of the storage group name.
• Addition of an Information Store to a storage group.
• Deletion of an Information Store from a storage group.
If you have performed any of the above operations, you will need to back up the Active Directory
and the Exchange database again. To perform a backup for the Active Directory, follow the in-
structions given in documentation provided by Microsoft.
• Performing any of the operations shown below changes the database name, and you will no
longer be able to restore and recover backup data obtained before these operations (that is, you
will no longer be able to use the
drmexgrestore or EX_DRM_EXG_RESTORE command with
the -recovery option specified):
• Repairing Information Store using the ESEUTIL utility ( ESEUTIL /p ).
