The fundamental step to managing the backup and restore functionality with Cisco UCS Manager domains registered with Cisco UCS Central, is creating domain groups. A domain group is a user-defined group or classification of domains that are added to Cisco UCS Central. You can manually add domains to an existing domain group using the Cisco UCS Central GUI or automatically by configuring a rule.
When you perform a backup using Cisco UCS Central, you can backup and restore Cisco UCS Central itself or backup and restore Cisco UCS Manager. and you can export the file to a location on your network. Database backup and full configuration export policies can be created under domain groups similar to other policies and from a Cisco UCS Manager perspective, they can be configured remotely or locally based on the backup control setting. For global backup policies, Cisco UCS Manager domains that are part of a domain group inherit the policy creation, update, and deletion events. Deleting these policies remotely resets the admin state to disabled in Cisco UCS Manager since these are global policies that cannot be completely deleted. You can schedule a backup and restore operation or you can perform an immediate backup and restore operation.
Remotely configured policies are restricted to use the Cisco UCS Central repository for backups which is internally mounted by Cisco UCS Manager. Local configurations allow you to specify any external backup server. You can use SCP, SFTP, FTP, and TFTP protocols.
Saved configurations can be used to restore and configure any managed Cisco UCS domain. In recovery situations, full-state backups can be used. TFTP can be used to access the backup configurations and you can use the Cisco UCS Central GUI or the CLI to copy the URL of the back up file and use it to configure a new domain.
You can perform a backup while the domain is up and running. The backup operation saves information from the management plane. It does not have any impact on the server or network traffic.
To manage the backup archives, you can specify the maximum number of backup versions that are saved. The policy specifications can be used to indicate the number of backups to maintain for each
Cisco UCS Manager domain. You can also view the list of backups for each
Cisco UCS Manager domain from the
Cisco UCS Central GUI and you can delete saved or unused backup directories and configurations.
You can delete backups only after a Cisco UCS Manager domain (from which the backup has been taken) has been unregistered.
