Cisco UCS Central enables you to backup and restore Cisco UCS Central and the registered UCS domains. You can schedule a backup and restore policy. You can also perform an immediate on-demand backup of Cisco UCS Central, or a selected domain.
From the Backup & Restore page, you can schedule a full state backup for Cisco UCS Central and the registered Cisco UCS Domains. For Cisco UCS domains, you can also create the full state backup policy locally.
Scheduled backup policies are disabled by default. If you want to back up Cisco UCS Central or the registered UCS domains, enable the backup state for both. The backup process does not interrupt or impact any server or network traffic. You can perform a backup while the domain is up and running. The backup operation saves information from the management plane.
Cisco UCS Central restricts remotely configured policies to using the Cisco UCS Central repository for backups, which is internally mounted by Cisco UCS Manager.
When you schedule a regular backup, the backup repository can start accumulating data. To manage the backup archives, you can specify the maximum number of backup versions that are saved. Use policy specifications to indicate the number of backups to maintain for each Cisco UCS domain.
Note | The maximum number does not impact the number of backup image files you can store on a remote location. |
You can view the list of backups for each Cisco UCS domain from the Cisco UCS Central GUI and you can also delete saved or unused backup directories and configurations.
You can save the database or configuration backup files in the following locations:
Local File System: In a local file system.
Remote Location: Remote locations using a protocol such as TFTP, FTP, SCP, or SFTP.
You must have Cisco UCS Manager, release 2.2(2x) and above, registered with Cisco UCS Central to specify a global backup policy with the option to store the image file in a remote location.
When you schedule the backup, you can also specify the maximum number of backup files that you want to save for either system.
You can restore the full state backup for Cisco UCS Central during setup only. For more information, see the appropriate Cisco UCS Central Installation and Upgrade Guide.
For Cisco UCS Manager, you can restore the full state backup configuration from the fabric interconnect's console during initial configuration.
Before you create a backup operation, consider the following:
The backup location is the destination or folder on the network where you want Cisco UCS Central to export the backup file. You can maintain only one backup operation for each location where you plan to save a backup file.
If you rerun a backup operation without changing the filename, Cisco UCS Central overwrites the existing file on the server. To avoid overwriting existing backup files, change the filename in the backup operation or copy the existing file to another location.
You can run and export more than one type of backup to the same location. Change the backup type before you rerun the backup operation. We recommend that you change the filename for easier identification and to avoid overwriting the existing backup file.
You can create a backup operation in advance and leave the admin state disabled, until you are ready to run the backup. Cisco UCS Central does not run the backup operation, save, or export the configuration file until you set the admin state of the backup operation to enabled.
You cannot perform incremental backups.
Full state backups are encrypted so that passwords and other sensitive information are not exported as clear text.
Port configurations that include global VLANs and VSANs are not restored when you do an all-config backup in Cisco UCS Manager. Reconfigure the ports from Cisco UCS Central.
You can perform one or more of the following types of backups in Cisco UCS Central:
Full-state— You can specify full state backup only during installation. Full state backup is a binary file that includes a snapshot of the entire system. You can use the file generated from this backup to restore the system during disaster recovery. You cannot use this file for an import.
Note | You can only use a full state backup file to restore a system that is running the same version as the system from which the backup file was exported. |
Config-all— All configuration back up is an XML file that includes all system and logical configuration settings. You cannot use this file for a system restore during installation.
Config-logical— Logical configuration back up is an XML file that includes all logical configuration settings. These include service profiles, VLANs, VSANs, pools, policies, users, locales, LDAP, NTP, DNS authentication and administration settings. You can use the file generated from this backup to import these configuration settings. You cannot use this file for a full state system restore during installation.
Config-system— System configuration back up is an XML file that includes statistics configuration and scheduler information. You can use the file generated from this backup to import these configuration settings. You cannot use this file for a full state system restore during installation.

You can create a full state backup for registered Cisco UCS domains only at the domain group level.
To watch a video on scheduling a backup, see Video: Creating Scheduled Backup for a UCS Domain.
To setup a manual backup, provide the Absolute remote path in this format: /path/filename.tgz
To setup a scheduled backup, provide the home folder path (/) without the filename. For SFTP, you must create the path and the required subfolders/directories in the SFTP server before you provide the home folder path. Exportation will fail if the folder is not setup in advance. For example, if you want to setup the home folder path of the SFTP server to C:\sftp, and if no other folder is present in the hierarchy, and if you provide the Absolute remote path as C:sftp\abc the exportation will fail because no such directory would be present in the system.
If you specify a remote location, make sure that location exists. Make sure to have the following information ready for saving backup file in the remote location:
You can create a full state backup for Cisco UCS Central at any time, and save the file in both local and remote locations. However, for registered Cisco UCS domains, you can create a backup on a remote location only.
