CNM Cyber

Databases of CNM Cloud (hereinafter, the Lectio) is the lesson part of the Cloud Foundation Essentials lesson that introduces its participants to CNM Cloud. This lesson belongs to the Introduction to CNM Cloud session of the CNM Cyber Orientation.


Content

The successor predecessor lectio is What the Foundation Is.

Key terms

Script

Every software system of CNM Cloud is supported by its own relational database management system (RDBMS).
WorldOpp Middleware collects most important data from various systems throughout the CNM Cloud Foundation, transforms the collected data in a unified format, and stores the data in its NoSQL database. The CNM Cyber Team decides on what data shall be collected, transformed, and stored.
To secure data from disasters such as computer failures and other data loss events, all the data is backed up at the same time every day. At CNM Cloud, that means that the database data is copied and stored separately from the computing server on which the database is installed. In that way, the data backup wouldn't be destroyed if one server collapses.
For different systems, the backup policies may vary, but the backup system always contains several copies of all data that the CNM Cyber Team considers worth saving. For instance, the system may contain backups that were made yesterday, a day before yesterday, last week, and last month. Commonly, one "old" backup is deleted when one new backup is made.
As a disaster recovery, any data copy can substitute the original data in the database. However, no data backup cannot restore the data that have been created after the backup was made.

Data in the Foundation is the successor lectio.
