Configuring Boot Devices for J Series Services Routers

You can configure a boot device to replace the primary boot device on your J Series or SRX Series device, or to act as a backup boot device. The backup device must have a storage capacity of at least 256 MB. Use either the J-Web interface or the CLI to take a snapshot of the configuration currently running on the device, or of the original factory configuration and a rescue configuration, and save it to an alternate medium.

Note: For media redundancy, we recommend that you keep a secondary storage medium attached to the J Series or SRX Series device and updated at all times.

If the primary storage medium becomes corrupted and no backup medium is in place, you can recover the primary CompactFlash card from a special 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 Routers Hardware Guide.
