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:
user@host>
show system information
- Enter the
request system snapshot
command. Use the verbose option to view information about the snapshot process.user@host>request system snapshot verbose
