The Manage>Snapshot page allows you to configure storage devices to replace the primary boot device on your router or to act as a backup boot device. To do so, you create a snapshot of the system software running on your router, saving the snapshot to an alternate storage device.
The Manage Snapshot page allows you to perform the following tasks:
Caution: We recommend that you keep your secondary storage medium updated at all times. If the internal compact flash fails at startup, the J-series routing platform automatically boots itself from this secondary storage medium. The secondary storage medium can be either an external compact flash or a USB storage device. When a secondary storage medium is not available, the routing platform is unable to boot and does not come back online. This situation can occur if the power fails during a JUNOS software upgrade and the physical or logical storage media on the routing platform are corrupted. The backup device must have a storage capacity of at least 256 MB.
Click Snapshot to begin.
Alternatively, you can use the request system snapshot command in the J-Web CLI terminal to take a snapshot of the routing platform. For information about installing boot devices, see the Getting Started Guide for your J-series router.
