Creating a Snapshot of Files on a C Series Controller

You can create a snapshot of the system software to serve as a backup. When you create a snapshot, the software backs up the operating system and the SRC software to a partition on the C Series Controller. You can restore the files in a snapshot to the system software if needed.

To create a snapshot of the system software:

  1. Verify which version of the software is running on the system.
    user@host> show system information
  2. Enter the request system snapshot command. Use the verbose option to view information about the snapshot process.
    user@host> request system snapshot verbose
    Create system snapshot [yes,no] ? (no) yes
