Cisco UCS Central enables you to backup
Cisco UCS Central itself and
the registered UCS domains. You can schedule backup
and restore policy or, you can perform an immediate backup
operation. There are two types of scheduled and immediate backup operations:
You can schedule the following backup policies separately for both Cisco UCS Central and Cisco UCS domains:
- Full state backup policy: Backs up database.
- Config all export policy: Backs up the configuration in XML format.
For a UCS domains, these policies can either be defined locally or defined in
Cisco UCS Central
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. 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.
policies are restricted to use the
Cisco UCS Central repository
for backups which is internally mounted by
Cisco UCS Manager.
When you schedule 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.
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 must have
a user account that includes the admin role to create and run backup and import
You can delete
backups only after a
Cisco UCS domain (from which the backup has been
taken) has been unregistered.
config-logical and config-system type backups are only supported in Cisco UCS Central on demand back up.
Backup Image Files
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 any one of the protocol such as, TFTP, FTP, SCP, or SFTP.
You must have Cisco UCS Manager, release 2.2(2x) in registered Cisco UCS domains to specify a global backup policy with the option to store the image file in a remote location. If you do not have Cisco UCS Manager, release 2.2(2x) in the Cisco UCS domain, the global backup policy with remote backup will not work.
When you schedule the backup, you can also specify the maximum number of backup files you want to save either for system.
You can use the saved configuration from backup repository to restore and configure any of the managed Cisco UCS domain. Make sure to use full-state backup for recovery situations. Use TFTP protocol to access the backup configurations. You can use both Cisco UCS Central GUI or CLI to copy the backup file URL and use it to configure a new domain.
