SnowMirror is a Smart Data Replication Tool for ServiceNow
How it works
The SnowMirror server is running as an agent service in your environment. It downloads data changes from a ServiceNow instance and updates a mirror database, according to the configured replication jobs. It uses out-of-the-box API available in every instance no changes are needed on the ServiceNow side.
All you need is a server with the agent installed and a mirror database (e.g. Oracle, MySQL, etc.). This database can be used for custom reporting, data warehouse load, system integration, backup and more.
