Managing backups and restores
You back up appliance configuration settings in the Backups/Restore page.
Backup and restore operations use hostname resolutions. You must have DNS configured for these operations to function correctly.
Typically, you don’t need to use backups. We recommend that you restore an appliance to health by resending its configuration policies. If using policies for restoration isn’t possible, you can use this procedure to restore the system to the backup restore point. However, the restore point doesn’t include SSL settings configured in the SSL page.
The SCC collects backups automatically, every day, at 3:00 AM, with the filename <yyyy>.<mm>.<dd><config-name>, where <config-name> is the name of the active configuration on the SteelHead.
Assigning rollover strategy
You assign a rollover strategy under Manage > Operations: Backup/Restore. You select the rollover strategy for the backups.
All backups for the last 30 days are kept, and for anything older only the first backup of the month is kept.
Under Appliance Snapshot Rollover Strategy, select the rollover strategy from the drop-down list:
Age-Limited
Keeps only the most recent backups. All backups for the last 30 days are kept and for anything older only the first backup of the month is kept.
Deduplicated
Keeps only the most recent backups.
Backing up appliance configuration settings
You can back up an appliance configuration from the SCC by creating a snapshot of the appliance CLI configuration settings under Manage > Operations: Backup/Restore.
Select the source appliance from the drop-down list. Specify the snapshot name to back up the appliance to the SCC, and click Backup.
User-generated backups must be removed manually; they’re not deleted automatically. Daily backups are automatically deleted as follows:
• The first automatic daily backup of the month is automatically deleted after three years.
• All other daily automatic backups are automatically deleted after thirty days.
Removing configuration backups
You can remove configuration backups under Manage > Appliances: Backup/Restore. Select the appliance from the Source Appliance drop-down list to display the configuration backups for the specified appliance. Select the check box next to the backup name and click Remove Selected Snapshots to remove the from the list.
Restoring an appliance configuration settings
You can restore an appliance configuration from the SCC under Manage > Operations: Backup/Restore by specifying the snapshot configuration name.
Select the source appliance from the drop-down list, and select the snapshot name that you want to restore to expand the page.
Optionally, you can select Include defaults and hidden commands; select Restore to a Different Appliance and select a different appliance from the drop-down list to change the appliance to restore; and select Restore Primary and Aux network interfaces.
To remove a snapshot from the restore list, select the check box next to the name and click Remove Selected Snapshot.
Migrating the current state of a source appliance
You can migrate the state (statistics, SCC configuration, snapshots) of the source appliance to a different appliance under Manage > Operations: Backup/Restore. Under Migrate Operation select the target appliance from the drop-down list; the source appliance will be deleted. You can migrate the state from one appliance to another in the Backup/Restore page. Click Migrate.
When you perform a migrate operation, SCC 9.0.x doesn’t update the domain join status or the hybrid network settings (that is, sites, path selection, secure transport, or QoS). You must update the domain and the hybrid network settings manually.
