A database disaster is an event that causes data loss or service interruptions. There can be numerous reasons for disasters, such as power failures, hardware failures, human error, and environmental disasters, among others. They are hard to predict and some of them are not preventable. Therefore, safeguarding data becomes a crucial issue for any enterprise application.
The Greenplum Disaster Recovery feature enables Point In Time Recovery (PITR) to recover the entire Greenplum cluster to a certain recovery point before the disaster. Greenplum Disaster Recovery provides disaster recovery capabilities for Greenplum Database based on WAL archiving. It allows you to perform full and incremental backups of a database cluster’s files, as well as do point-in-time-recovery (PITR) from backups.
