A snapshot allows you to back up the associated object data according to the configured backup policy. Currently, it can be associated with a security group, so that you can back up the outbound and inbound rules of the associated security group. This feature is an auxiliary feature, which does not affect operations on security groups.
Scenarios
If you need to frequently update your security group rules, we recommend you configure a snapshot policy for the security group and promptly back up the security group rules. When the newly modified rules are abnormal, you can use the snapshot rollback feature to roll back to the original rules, thus ensuring business availability.
