The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter includes the following sections:
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 or you can 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 backup Cisco UCS Central or the registered UCS domains, you must 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.
Remotely configured policies are restricted to use 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 you want to save either for 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. You need to change the backup type before you rerun the backup operation. We recommend that you change the filename for easier identification of the backup type 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 of Cisco UCS Manager or Cisco UCS Central.
Full state backups are encrypted so that passwords and other sensitive information are not exported as clear text.
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:
Step 1 | In the Task
bar, type
Schedule Central Backup and press Enter.
This launches the Schedule Central Backup dialog box. | ||||||||||||
Step 2 | (Optional) In the Description field, enter a description for this backup policy. | ||||||||||||
Step 3 | From the
Schedule drop down, choose a schedule for this
backup. This can be one of the following:
| ||||||||||||
Step 4 | In
Maximum
No of Backup Files field, specify the number of backup files you
want to keep in the system.
After the maximum number of backup files is reached, the oldest backup file is overwritten by the newest backup file. | ||||||||||||
Step 5 | (Optional)If you want to
save the backup file in a remote location, in the
Remote
Copy filed, click
Enabled.
|
You can create full state back for registered Cisco UCS Domains only at the domain group level.
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 back up on a remote location only.
Make sure you have the following information ready to save the on-demand backup file in a remote location:
Step 1 | On the menu bar, click the Operations icon and select Backup & Restore. |
Step 2 | Click UCS Central or select a domain group. |
Step 3 | Click the
Backup icon.
This launches the Create Backup dialog box. |
Step 4 | For a
Cisco UCS Central
full state backup, choose whether to enable or disable
Remote Copy.
If you select Disabled, a local backup copy will be made, and you can proceed to step 6. |
Step 5 | Select the Transfer Protocol, and entire the required remote location information. |
Step 6 | Click Create. |
The full state backup file is created and saved in the specified remote location. To view the backup state for Cisco UCS Domains, click the domain group name.
![]() Note | End point timed out. Check for IP, password, space or access related issues.To fix this error, you can resubmit the configuration. On successful re-submission, a backup file is created in the backup repository. |
Step 1 | On the menu bar, click the Operations icon and select Backup & Restore. |
Step 2 | Click the
