Backing up and restoring an appliance
The SCC automatically performs a configuration backup (snapshot) of the managed appliances. The backup occurs during the maintenance window (1:00 A.M. to 4:00 A.M. by default). To display the Maintenance Window page, choose Administration > Maintenance: Maintenance Window.
If you use web proxy, it might be necessary to configure a proxy whitelist to enable direct SCC to SteelHead access for backups. See the SCC Best Practices chapter of the SteelCentral Controller for SteelHead User Guide.
To back up the configuration of a managed appliance
1. Choose Manage > Operations: Backup/Restore.
2. Select a Source Appliance and enter a snapshot name.
3. Click Backup. The backup is stored on the SCC.
When you back up and restore a SteelHead, the SCC only backs up the legacy configuration. QoS, path selection, and secure transport configurations aren’t backed up to or restored from a SteelHead.
To restore from a backup
1. Choose Manage > Operations: Backup/Restore.
2. Select a source appliance from the drop-down menu.
3. Enter the snapshot name to restore from and the target appliance.
4. Click Restore.
We recommend that you also perform a policy push to restore the configuration stored in the SteelHead secure vault.
Restoring the backup to the source appliance is useful for rolling back configuration changes. As a best practice, create a manual backup before any major configuration changes. You can restore a backup from one appliance to another; the restore operation only restores the appliance configuration.
As a best practice, use the migrate operation when moving a configuration between compatible appliances (SteelHeads, Interceptors, Client Accelerator, and Cores). The migrate operation moves statistics and an SCC configuration from one appliance to another, including snapshots. The source appliance is deleted after a successful migration. The destination appliance RiOS version must be equal to or greater than the source appliance RiOS version.
