Cloud Resolver includes an endpoint that creates a snapshot of the current DNS zone and resource record information, and configuration information of Cloud Resolver. In the event of a failure, you can restore the snapshot to recover the latest saved state of Cloud Resolver.
To create a snapshot, access the following Cloud Resolver endpoint URL:
http://<cloud_resolver_ip_or_hostname>:9050
Once you have accessed the endpoint, a snapshot is created and saved within the /var/lib/bluecat directory. If you configured a custom snapshot directory, the file is saved to that directory.
The snapshot is stored as a gzip compressed JSON file. Once you have created the snapshot, contact BlueCat Customer Care for assistance with troubleshooting and restoring Cloud Resolver from a snapshot.
Automatically creating snapshots
In the Cloud Resolver configuration file, you can configure the
CRS_SNAPSHOT_AUTOGENERATE configuration parameter to
true. When this is configured, Cloud Resolver automatically creates a
snapshot every time a change in discovered in the cloud environment.
For more information on configuring automatic snapshot creation, refer to Creating the Cloud Resolver configuration file.
