HP P9000 Replication Manager Software 7.3.1-00 Application Agent CLI Reference Guide

Description
This extended command backs up a file system from the primary volume to the secondary volume;
the file system has the operation ID specified by executing the drmfsbackup command. At this time,
the EX_DRM_FS_BACKUP command generates a backup ID.
Prerequisites
The prerequisite for executing this extended command is as follows:
• An operation definition file linked to the specified operation ID has been provided.
Arguments
operation-ID
A character string that uniquely identifies the operation to be performed. Information in the operation
definition file corresponding to the specified operation ID is used when executing the extended
command.
-mode online
Specify this option to perform online backup. The online backup method backs up a file system without
unmounting it.
If you specify online backup for a file system, this extended command only synchronizes the file system
before the online backup. To ensure consistency in the backup data, you need to suppress the updating
of data before backup processing.
Even if you omit this option, an online backup is the default.
-mode cold
Specify this option to perform cold backup.
Use a cold backup for a mounted file system. When executed, this extended command unmounts the
specified file system and backs up the volume in offline mode. After backup processing has finished,
the command mounts the file system again. If unmounting of the file system fails, the command displays
an error message and cancels backup processing. If the target volume has already been unmounted,
the command cancels backup processing.
If executed on a server with a cluster configuration, this extended command takes the target disk
resource offline instead of unmounting the file system, and then backs up the volume. When backup
processing is completed, the command brings the target disk resources online again.
Backup processing is canceled if the command is executed in the following cases:
• An attempt to take the disk resource offline fails.
• The disk resource is already offline.
-mode vss
Specify this option to perform VSS backup.
To use this option, the Protection Manager service must be running on the backup server.
-comment backup-comment
Specify this option to register a backup comment in the backup catalog. The conditions for specifying
a value in the backup-comment parameter are as follows:
• The value must be 64 bytes or less.
• The value can include alphanumeric, reserved, one-byte space, and multi-byte characters.
