• The files to be backed up must all be placed on a RAID volume defined as a pair.
• For Exchange 2003/2007 servers, deploy the storage group taking into consideration that backups
are conducted in units of volumes. If you deploy multiple storage groups in the same 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 volume.
• When you place an Exchange database that is subject to backup on a volume, note the following:
• You cannot put the transaction log file (
*.log ) on a volume where data files are stored.
• Data files ( *.edb , *.stm ) and checkpoint files ( *.chk ) cannot be allocated to the same
volume.
• Do not use the following characters when setting a name for a storage group: = ; \ / “ ,
• Do not register the instances of multiple Exchange resources into a cluster group.
• If a mounted storage group or information store is renamed in Exchange Server 2003/2007, all
of the information stores under the corresponding storage group must be unmounted and then re-
mounted.
• If an information store is renamed in Exchange Server 2010/2013, the information store must be
unmounted and then remounted.
• Exchange Server 2010/2013 recovery information stores are not backed up. Recovery information
store files and folders must be located on a different file system from the information stores.
• To back up a storage group in Exchange Server 2003/2007, the information stores in the storage
group must be mounted.
• To back up information stores in Exchange Server 2010/2013, the information stores must be
mounted.
• Backup and restore operations cannot be performed in an environment in which the Automatic
Reseed feature of Exchange Server 2013 is enabled.
• If you back up a passive mailbox database and then perform a point-in-time restoration from that
backup, the restored data might be older than the data you intended to back up.
To prevent such symptom, do the following when you back up a passive mailbox database:
1. Stop the database copy.
2. Reseed the database.
3. Back up the database copy.
Exchange Server backup requirements
The Exchange Information Store service and the Microsoft Exchange Replication service (Exchange
Server 2013 only) must be running to perform a VSS backup. In addition, all information stores to
be backed up must be mounted.
During backup, write processing to the Exchange Server databases is stopped for approximately 10
seconds. This means that operations involving database write processing (such as email transmissions)
are temporarily stopped.
Exchange Server restore requirements
For Exchange Server 2013, before you restore the database, you need to stop the Microsoft Exchange
Search Host Controller service on the database server.
The following symptoms might occur while the Microsoft Exchange Search Host Controller service
terminates:
• You cannot search for items using Outlook Web App and Outlook (online mode).
