Figure 24 Metafile allocation (in the cluster configuration)
Using a dynamic disk configuration
• Do not allocate a data file made up of multiple instances to a file system (drive) of a disk group
subject to backup and restoration.
• Allocate the following directories and files to a file system (drive) of a disk group different from
the one to which data files (*.mdf and *.ndf) are allocated. If these directories and files are
allocated to a file system (drive) of the same disk group, an error will occur when backup is ex-
ecuted.
• Metafile storage directory (only if a VDI metafile storage directory was specified with the
drmsqlinit command)
• Backup data of the transaction log
• To allocate a file that is made up of multiple databases to a file system (drive) of the same disk
group, you must collectively back up and restore all the databases. If these requirements are not
met when performing Application Agent backup, backup processing terminates with an error.
• To back up or restore databases individually, allocate database data files to a file system (drive)
of a different disk group.
Using a cluster configuration
• Do not register the service resources of multiple SQL Server instances into a cluster group.
• In a cluster environment, specify a user on each node for the owner of a database subject to
backup. Local users with the same user name and password on different nodes are not considered
to be the same user. Therefore, use a domain user account that is common to all nodes. If failover
is performed to a node where the database-owner user does not exist, backup fails because the
database owner is unknown.
• In a cluster environment, install an SQL Server instance as a failover cluster.
