Provides information about how the system manages snapshots for cloud-hosted control components, retention periods, on-demand snapshots, and limitations.
The system takes regular snapshots of cloud-hosted Cisco SD-WAN Manager control components that we manage, based on the snapshot frequency. By default, the snapshot frequency is once every day, typically at midnight of the region of deployment, and the system retains the last seven snapshots. You can set the snapshot frequency to values between once a day to once every four days. To learn more about snapshots, refer to Information About Snapshots in the Cisco Catalyst SD-WAN Portal Configuration Guide.
Open a Technical Assistance Center (TAC) support case to review the current snapshot setting, or use the Cisco Catalyst SD-WAN Portal to change it. You can retain a maximum of seven periodic snapshots.
Snapshots are stored in your cloud account and cannot be downloaded. However, you can download the config-db backup file from Cisco SD-WAN Manager and save the configurations, including the templates, with the command request nms configuration-db backup path.
Since Cisco SD-WAN Validator and Cisco Catalyst SD-WAN Controller are stateless, snapshots are not captured. Use a Cisco SD-WAN Manager template to configure and save Cisco SD-WAN Validator and Cisco Catalyst SD-WAN Controller configuration settings.
On-demand snapshots
You can only use the on-demand snapshot process for fabrics with Cisco-hosted, cloud-based, dedicated, single-tenant control components. This is not applicable if you have a shared tenant fabric.
For any major planned change windows for Cisco SD-WAN Manager, you can take on-demand snapshot using Cisco Catalyst SD-WAN Portal. You can request this by opening a TAC support case with the CloudOps team. Freeze configuration changes and allocate up to eight hours prior to the change window to allow the on-demand snapshot to be taken and completed. You can store only one on-demand snapshot at a time for up to ten days from the creation date. If you create a new on-demand snapshot, the system removes and replaces the previous snapshot.
