Backing up and restoring a file system
•
When the backup is of an SQL Server database:
Backing up and restoring an SQL Server database
•
When the backup is of an Exchange database:
Backing up and restoring a storage group
Precautions on operations
•
When using Application Agent in a cluster configuration, specify the same instance in the RAID
Manager linkage definition file (
DEFAULT.dat
) as the instance for the active server and standby
server.
•
Run Application Agent after starting the backup server instance. If the backup server instance is
not running, RAID Manager commands will terminate in an error.
•
Do not use Application Agent commands to change the configuration while a RAID Manager
command is executing. Also, do not execute RAID Manager commands while Application Agent
commands are executing.
Additional explanation
Internally, Application Agent use the CLI function of RAID Manager. When you are using
commands provided by RAID Manager to change the status or the configuration of pair
volumes, you must ensure that Application Agent is not operating.
•
When you use RAID Manager commands to change the configuration of pair volumes, you must
revise the settings so that the configuration matches the conditions for execution of Application
Agent commands, and you must also update the dictionary map files.
•
If you are rebooting a system that references the secondary volume, the secondary volume might
be mounted automatically.
If this happens, use the disk management utility provided by the OS to manually unmount the
automatically mounted secondary volume to be used in backup and restore processing. This oper-
ation must be performed before you use Application Agent commands.
Precautions on backup and restoration
•
Depending on the backup method, you might not be able to perform restoration, even if there is
backup data on the secondary volume.
The following is a description of an example of two objects
#
subject to backup stored in separate
volumes:
• Database A (copy group:
vg01,obj01
)
• Database B (copy group:
vg01,obj01
)
Use the following backup method to back up the databases:
1.
Back up database A and database B concurrently.
The backup ID
0000000001
is created.
2.
Back up database A only.
The backup ID
0000000002
is created.
#
The objects subject to backup are as follows:
When the backup is of a file system: mount point.
When the backup is of an SQL Server database: database.
When the backup is of an Exchange database: storage group or Information Store.
