Data at CNM Farms (hereinafter, the Lectio) is the lesson part of the CNM Farm Essentials lesson that introduces its participants to Opplet. This lesson belongs to the Introduction to CNM Cloud session of EmployableU Concepts.
Content
The predecessor lectio is CNM Cloud Databases.
Script
- Most of end-user applications of Opplet are supported by their own relational database management systems (RDBMSes).
- WorldOpp Middleware collects most important data from various systems throughout the CNM Farms, transforms the collected data in a unified format, and stores the data in its NoSQL database. CNMCyber 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 Opplet, 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 CNMCyber 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 of CNM Lab Farm, which is used for experiments, is periodically destroyed. Data of CNM HandsOn Farm, which support hands-on training, is destroyed upon one's course completion.
Key terms
Closing
- Would you like to work for data backup procedures in Opplet?--- Yes/No/I'm not sure
Clusters in CNM Farms is the successor lectio.
