•
The backup server is required even if data is not backed up to tape. This is because the backup
server imports VS snapshots and verifies the Exchange database.
•
If Veritas Snapshot Provider is installed on the database server or backup server where a VSS
backup will be performed, make sure you use version Veritas Snapshot Provider 1.04 or later.
If a VSS backup is executed using version Veritas Snapshot Provider 1.03 or earlier, the volume
to be backed up might be left with
Read-Only
and
Hidden
attributes. If this happens, the drive
will not be allocated at system startup and Exchange Server will not operate normally. If this occurs,
release these attributes as described in Microsoft Knowledge Base Article 840781.
•
If a system failure or other problem causes a VSS backup to be interrupted, the volume that is the
target of the backup might be left with the
Read-Only
and
Hidden
attributes. If these attributes
remain, the drive will not be allocated at system startup, and Exchange Server will not operate
normally. If this occurs, release the attributes as per Microsoft Knowledge Base Article 840781.
•
If you want to perform a VSS backup, perform a restoration, or delete transaction logs while Ex-
change Server is operating, you must make sure that certain services are running. The services
that must be running differ depending on the version of Exchange Server.
For Exchange Server 2003, Exchange Server 2007, or Exchange Server 2010:
Microsoft Exchange Information Store Service must be running.
For Exchange Server 2013:
Microsoft Exchange Information Store Service and Microsoft Exchange Replication Service
must be running.
•
During backup, the database write processing of Exchange Server shuts down for a certain period
(up to 10 seconds). During that period, the database write processing of Exchange Server (such
as sending mail) is suspended. After backup finishes, the database write processing of Exchange
Server is resumed.
•
Since the number of log files might increase during backup operations by VSS, when you perform
backup by using VSS, the backup results might contain a log file that has not been recorded in
the catalog.
•
Set the environment of Application Agent to use VSS. For details on environment settings required
to use VSS, see “
Specifying settings for using VSS
•
The Information Stores of the storage group that are to be backed up must all be mounted in ad-
vance.
•
When Protection Manager version 4.4 or earlier is used to back up storage groups, the Information
Stores of storage groups to be restored must all be mounted in advance. When Protection Manager
version 5.5 is used, the Information Stores do not need to be mounted in advance in order to be
restored.
•
If the name of the Exchange database has been changed, you must perform the following opera-
tions:
• For Exchange Server 2003 or Exchange Server 2007, unmount all of the Information Stores
in the relevant storage group and then remount them.
• For Exchange Server 2010 or Exchange Server 2013, unmount and then remount the Inform-
ation Stores.
•
Do not use LUN#0 as a secondary volume for the backup destination. If the LUN#0 disk is used
as a secondary volume for the backup destination, other disks might not be recognized.
•
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, as a backup metadata file necessary
for restoration is stored in it. This folder is automatically deleted after data has been restored.
•
Do not mount another volume in a directory on the volume to be backed up. If another volume is
mounted, mounting and restoration for the secondary volume might fail.
