You can configure a boot device to replace the primary boot device on your Services Router, or to act as a backup boot device. Use either the J-Web interface or the CLI to take a snapshot of the configuration currently running on the router, or of the original factory configuration and a rescue configuration, and save it to an alternate medium.

For media redundancy, we recommend that you keep a secondary storage medium attached to the Services Router and updated at all times. |
If the primary storage medium becomes corrupted and no backup medium is in place, you can recover the primary compact flash from a special JUNOS software image. You can also configure a boot device to store snapshots of software failures, for use in troubleshooting.
For information about installing boot devices, see the J-series Services Router Getting Started Guide.
