Backup Management

Backup and Restore

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.

Important:

  • You must have a user account that includes the admin role to create and run backup and import operations.

  • You can delete backups only after a Cisco UCS domain (from which the backup has been taken) has been unregistered.

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 a protocol such as TFTP, FTP, SCP, or SFTP.

    Important:

    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.

Restoring Configuration

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.

Considerations and Recommendations for Backup Operations

Before you create a backup operation, consider the following:

Backup Locations

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.

Potential to Overwrite Backup Files

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.

Multiple Types of Backups

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.

Scheduled Backups

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.

Incremental Backups

You cannot perform incremental backups of Cisco UCS Manager or Cisco UCS Central.

Encryption of Full State Backups

Full state backups are encrypted so that passwords and other sensitive information are not exported as clear text.

Backups from Cisco UCS Manager

Port configurations that include Global VLANs and VSANs are not restored when you do an all-config backup in Cisco UCS Manager. You will need to reconfigure the ports from Cisco UCS Central.

Scheduling a Full State Backup for Cisco UCS Central

To watch a video on scheduling a backup, see Video: Creating Scheduled Backup for UCS Central.

Before You Begin

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:

  • Absolute remote path. For example if the transfer protocol is SCP: scp://user@<ip>/x/y/z

  • Host name or IP address of the remote server

  • Username and password for the remote server

    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:

    • One Time Schedules—The backup occurs at the scheduled date and time only.

    • Recurring Schedules—The backup occurs at the scheduled frequency.

    Note   

    You must associate this full state backup with a pre-defined schedule. To create a schedule, see Creating or Editing a Schedule.

    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.
    Complete the following fields to add the remote location related information.

    Name

    Description

    Transfer Protocol

    Choose the transfer protocol. it can be one of the following:

    • FTP

    • SFTP

    • TFTP

    • SCP

    Scheduling a Full State Backup for Cisco UCS Domain

    • 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.

    Before You Begin

    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:

    • Absolute remote path. For example if the transfer protocol is SCP: scp://user@<ip>/x/y/z

              Configuration Export and Import

              From the Export & Import, you can schedule configuration backup for Cisco UCS Central and the registered Cisco UCS Domains. You can schedule export or import policy or, perform an immediate on demand configuration export of Cisco UCS Central or a selected domain. For a Cisco UCS domain, on demand backups are all stored remotely. If you schedule a backup, it can be stored locally or remotely.


              Note

              In the HTML5 GUI, only the config-all and full-state backups are supported. If you want to use the config-logical or config-system backups, please use the Java-based GUI.

              Scheduled backup policies are disabled by default. If you want to backup Cisco UCS Central or the registered Cisco 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.

              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 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 (See: Viewing Backup files in Cisco UCS Central), and you can also delete saved or unused backup directories and configurations.

              Important:

              • You must have a user account that includes the admin role to create and run backup and import operations.

              • You can delete backups only after a Cisco UCS domain (from which the backup has been taken) has been unregistered.

              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.

                Important:

                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.

              Importing Configuration

              You can use the saved configuration from backup repository to import and configure any of the managed Cisco UCS domain. Use TFTP protocol to access the backup configurations.
