Backup Data Type
Cisco ISE allows you to back up data from the primary PAN and from the Monitoring node. Backup can be done from the CLI or user interface.
Cisco ISE allows you to back up the following type of data:
Configuration data—Contains both application-specific and Cisco ADE operating system configuration data. Backup can be done via the primary PAN using the GUI or CLI.
Operational Data—Contains monitoring and troubleshooting data. Backup can be done via the primary PAN GUI or using the CLI for the Monitoring node.
When Cisco ISE is run on VMware, VMware snapshots are not supported for backing up ISE data.
Cisco ISE does not support VMware snapshots for backing up ISE data because a VMware snapshot saves the status of a VM at a given point in time. In a multinode Cisco ISE deployment, data in all the nodes are continuously synchronized with current database information. Restoring a snapshot might cause database replication and synchronization issues. Cisco recommends that you use the backup functionality included in Cisco ISE for archival and restoration of data.
Using VMware snapshots or any third-party backup service to back up Cisco ISE data might result in interrupting Cisco ISE services. When a backup is initiated by VMware or any other third-party backup service like CommVault SAN level backup, it quiesces the file system to maintain crash consistency, which can cause your Cisco ISE functionalities to freeze. A reboot is required to resume the services on your Cisco ISE deployment.
Restore operation, can be performed with the backup files of previous versions of Cisco ISE and restored on a later version. For example, if you have a backup from an ISE node from Cisco ISE, Release 1.3 or 1.4, you can restore it on Cisco ISE, Release 2.1.
While recreating a deployment after backing up and restoring data, a Context Visibility Reset of both Primary PAN and Secondary PAN are required to ensure that data on both the nodes are synced.
Cisco ISE, Release 2.3 supports restore from backups obtained from Release 2.0 and later.
