About Backup and Restore
You can use the backup and restore functions to create backup files to restore to a different appliance (if required for your network configuration).
Backup
You can back up automation data only or both automation and Assurance data.
Automation data consists of Cisco DNA Center databases, credentials, file systems, and files. The automation backup is a full backup.
The Assurance data consists of network assurance and analytics data. The first backup of Assurance data is a full backup. After that, backups are incremental.
Important |
Do not modify or delete the backup files. If you do, you might not be able to restore the backup files to Cisco DNA Center. |
Cisco DNA Center creates the backup files and posts them to a remote server. Each backup is uniquely stored using the UUID as the directory name. For information about the remote server requirements, see Backup Server Requirements.
Only a single backup can be performed at a time. Performing multiple backups at once is not supported.
When a backup is being performed, you cannot delete the files that have been uploaded to the file service, and changes that you make to these files might not be captured by the backup process.
We recommend the following:
-
Perform a daily backup to maintain a current version of your database and files.
-
Perform a backup after making changes to your configuration, for example, when changing or creating a new policy on a device.
-
Perform a backup only during a low-impact or maintenance period.
You can schedule weekly backups on a specific day of the week and time.
Restore
You can restore the backup files from the remote server using Cisco DNA Center.When you restore the backup files, Cisco DNA Center removes and replaces the existing database and files with the backup database and files. While a restore is being performed, Cisco DNA Center is unavailable.
You cannot do a backup from one version of Cisco DNA Center and restore it to another version of Cisco DNA Center. You can only restore a backup to an appliance that is running the same Cisco DNA Center software release with the same first four digits and the same application versions as the appliance from which the backup was taken. To view the current applications and versions, choose and click Currently Installed Applications.
You can restore a backup to a Cisco DNA Center appliance with a different IP address. This situation could happen if the IP address is changed on Cisco DNA Center and you need to restore from an older system.
Important |
After a backup and restore of Cisco DNA Center, you need to access the Integration Settings page and update (if necessary) the Callback URL Host Name or IP Address. For more information, see Configure Integration Settings. |
Backup and Restore Event Notifications
You can receive a notification whenever a backup or restore event takes place. To configure and subscribe to these notifications, complete the steps described in the Cisco DNA Center Platform User Guide's "Work with Event Notifications" topic. When completing this procedure, ensure that you select and subscribe to the SYSTEM-BACKUP and SYSTEM-RESTORE events.
A notification is generated and sent whenever one of the events listed in the following table occur:
