•
Do not use LUN#0 as a secondary volume for the backup destination, or other disks may not be
recognized.
•
To back up an SQL Server instance, the instance must be online. If an attempt is made to back up
an instance when it is not running, the attempt will fail.
•
If an instance contains multiple databases, the way volumes can be replicated or restored differs
as follows, depending on the configuration of the primary volumes containing the databases:
• When the databases are stored in the same volume, they can be replicated or restored at the
same time.
• When the databases are stored on different volumes, only some of the databases within the
instance can be replicated or restored.
•
Do not mount another volume in a directory on the volume to be backed up. If another volume is
mounted, mounting and restoration of the secondary volume may fail.
•
When data is backed up, a folder named
DRMVSSMETADATA_backup-ID
is created in the root
directory of the secondary volume. Do not delete this folder because it contains metadata necessary
for restoration. This folder is automatically deleted after data has been restored.
•
If you are running the Windows Disk Management application on Windows 2003 server without
a service pack installed, close the Disk Management application before creating the replica. If
the backup operation is executed while the Disk Management application is running, it might fail.
•
On Exchange 2003/2007, you cannot back up individual information stores. In addition, the
information stores of the storage group to be backed up must be mounted in advance.
•
On Exchange 2010/2013 (which does not use storage groups), all information to be backed up
must be mounted in advance.
•
You cannot back up storage groups extending across multiple database servers.
•
The recovery storage groups for Exchange Server 2003/2007 cannot be backed up. The files
and folders that make up the restoration storage group must be placed on a different file system
from the storage groups to be backed up.
•
Among the cluster resource groups, the Exchange System Attendant resource and the Exchange
information store resource must be online during backup. If they are not online, the backup oper-
ation will result in an error.
•
The operations shown below change information pertaining to the Exchange 2003/2007 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:
• 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 of the Active Directory database, follow
the instructions in the Microsoft documentation.
•
The following event log messages might be output to a backup server:
Event type: Error
Event source: PlugPlayManager
