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

Application Agent can back up only the database configuration files (the *.mdf and *.ndf data
files and the *.ldf transaction log file) and metafiles. Metafiles are generated when the backup
command is executed.
For database configuration files that are not subject to backup and for general files, no freezing
processing is executed. Therefore, if the primary volume contains a file that is not subject to the freezing
processing, pair partitions will be duplicated during file writing, resulting in loss of database integrity.
Allocate only the database configuration files subject to the freezing processing in the primary volume.
Allocation of database configuration files is shown in the figure below.
Figure 42 Allocation of database configuration files
Allocating multiple database configuration files to one volume
When multiple database configuration files are allocated to a volume, all databases need to be
backed up or restored in a group.
The figure below shows how backup and restoration are performed in this case.

Allocating metafiles
A metafile is a file SOL Server outputs during backup processing. Metafiles store information about
database composition and are therefore used in restoration processing.
If you have specified a VDI metafile storage directory by using the drmsqlinit command, when
backup data of the secondary volume is backed up to tape, the metafile must also be backed up to
the tape (this is not necessary if the metafile is stored in the same directory as the database file).
