command
in EXEC or administration EXEC mode.

Syntax Description
Defaults
The operation is performed in synchronous mode.
The backup files are copied to the secondary device defined with the
command.
The backup files are copied to the target device on the current secure domain router system controller
(DSDRSC).
Command Modes
EXEC
Administration EXEC
target-device
(Optional) Specifies the storage device used for the system backup. If a
target device is not specified, then the secondary device defined with the
command is used. If a target device is not specified
with either command, then the
system backup
command returns an error.
•
The target device cannot be the current boot device.
•
The target device must be large enough to store the current software set
and configuration.
•
The supported storage devices are
disk0:
and
disk1:
(if installed).
format
(Optional) Formats a target disk that already contains a system backup.
By default, the
system backup
command formats the target disk if that target
disk does not contain a previous system backup. If the target disk already
contains a backup, then the disk is not formatted again. The
format
keyword
forces a format of the target device even if it contains a previous system
backup.
location
node-id
(Optional) Specifies an alternative node location for the backup target disk,
such as the standby DSDRSC.
By default, the backup files are copied to the target device in the current
DSDRSC. Use the
location
node-id
keyword and argument to specify an
alternative node for the backup files, such as the standby DSDRSC.
The
node-id
argument is expressed in
rack
/
slot
/
module
notation.
location
all
(Optional) Backs up the software and configuration files to all RPs in the
router. Each RP must contain a disk in the specified target device location,
such as disk1.
asynchronous
(Optional) Performs the command in asynchronous mode. In asynchronous
mode, the command runs in the background, and the EXEC prompt is
returned as soon as possible.
synchronous
(Optional) Performs the command in synchronous mode. This mode allows
the installation process to finish before the prompt is returned. This is the
default mode.
