A checkpoint a copy of the master configuration. To be a bit more precise, a checkpoint is a copy of the master configuration XML files. You create a checkpoint so that you can roll back to a prior master configuration in the event that a change made to the master configuration produces some problem.
For example, you could create a checkpoint named Checkpoint001.
Lets say an application is mistakenly removed. In this example, the query application is removed.
Once removed, the query application is no longer listed.
The prior checkpoint can be restored to return to the configuration that included the application that was removed. In this example, Checkpoint001 includes the query application.
Once the restore has completed, you will need to sign out and then back into the web console.
Once signed back into the web console, the query application has been successfully restored.
There are two types of checkpoints.
