This article describes the purpose and output of the show system auto-snapshot operational command, which reports the status of automatic configuration and system snapshots generated by Junos OS to assist in system recovery.

Auto-snapshot is a preventive mechanism that ensures system recoverability. When enabled, the device automatically creates and maintains rescue snapshots of the /config and system partitions, making it easier to boot from a known-good state in the event of storage corruption, unexpected reboots, or hardware issues.

user@switch> show system auto-snapshot

Auto-snapshot Configuration: Enabled
Auto-snapshot State: Disabled

Status of the configuration:

Enabled—If the system reboots from the alternate partition, the automatic snapshot feature automatically takes a snapshot of the alternate partition and copies it onto the primary partition.

Disabled—The system does not automatically take a snapshot of the alternate partition. You must use the manual snapshot command, request system snapshot, to take a snapshot of one partition and copy it onto the other.

Status of the automatic snapshot procedure:

Completed—The automatic snapshot procedure has completed copying the alternate partition to the primary partition and the alarm has been cleared.

Disabled—The automatic snapshot procedure is inactive.

In progress—The automatic snapshot procedure is in progress. It takes about 10 to 15 minutes to complete, depending upon disk size.
