HP StorageWorks P9000 Replication Manager Software 7.1 CLI User Guide (TB584-96026, May 2011)

• For online backup and VSS backup, data files (*.edb, *.stm) and checkpoint files (*.chk)
cannot be allocated to the same volume.
In Exchange Server 2010:
• 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).
• Defragmentation using the ESEUTIL utility (ESEUTIL /d).
If you have performed any of these operations, you will have to execute the drmexgbackup or
EX_DRM_EXG_BACKUP command, and then back up the Exchange database again.
• You can use a circular log only when using Exchange Server 2003 to perform a cold backup or
online backup. However, if you use a circular log, the oldest log among the existing log files is
deleted when a new log file is created. This means that some logs might disappear at roll-forward.
For this reason, when performing roll-forward recovery, do not use a circular log.
• The recovery storage groups for Exchange Server 2003 and Exchange Server 2007 cannot be
backed up. The files and folders that make up the recovery storage group must be placed on a
different file system from the storage groups to be backed up.
• The recovery database for Exchange Server 2010 cannot be backed up. The files and folders that
make up the recovery database must be placed on a different physical volume from that of the
database to be backed up.
• When using Snapshot, you cannot perform a backup to tape by using Application Agent. So,
when using Snapshot, use another backup product to back up (to tape) an Exchange database
that is on the primary volume.
• When using Exchange Server 2007 and Exchange Server 2010, only VSS backup can be used.
• Of the high-availability functions in Exchange Server 2007, only SCC, CCR, and SCR are suppor-
ted. LCR is not supported.
