Release Information
Command introduced in Release 10.2 of Junos OS.
Description
Back up the currently running and active file system partitions on the device.
Options
- factory— (Optional) Specifies that only the files shipped from the factory are included in the snapshot.
- media— (Optional) Specifies the media to be included
in the snapshot:
- compact-flash— Copies the snapshot to an external compact flash.
- hard-disk— Copies the snapshot to a hard disk.
- usb— Copies the snapshot to the USB storage device.
- internal— Copies the snapshot to internal media. This is the default.
Note: USB option is available on all SRX series devices; hard disk and compact-flash options are available only on high-end SRX series devices; media internal option is available only on branch SRX series devices.
- node— (Optional) Specifies to archive the data and
executable areas of a specific node.
- node-id—Archive a specific node. The range of node ID is (0,1)
- all—Archive all nodes.
- local—Archive only local nodes.
- primary—Archive only primary nodes.
- partition - (Default) Specifies that the target media
should be repartitioned before the backup is saved to it.
Note:
- The target media is partitioned whether or not it is specified in the command, because this is a mandatory option.
- You cannot partition a hard-disk as it is mounted on /var directory.
- slice— (Optional) Takes a snapshot of the root
partition the system has currently booted from to another slice in
the same media.
- alternate— (Optional) Stores the snapshot on the other root partition in the system.
Note:
- The slice option cannot be used along with the other request system snapshot options, because the options are mutually exclusive. If you use the factory, media, or partition option, you cannot use the slice option; if you use the slice option, you cannot use any of the other options.
- The slice partition is supported only on branch SRX Series devices.
