Database backup is the process of backing up the operational state, architecture and stored data of database software. It enables the creation of a duplicate instance or copy of a database in case the primary database crashes, is corrupted or is lost.
Database backup is a way to protect and restore a database. It is performed through database replication and can be done for a database or a database server. Typically, database backup is performed by the RDBMS or similar database management software. Database administrators can use the database backup copy to restore the database to its operational state along with its data and logs. The database backup can be stored locally or on a backup server.
Database backup is also created/performed to ensure a company’s compliance with business and government regulations and to maintain and ensure access to critical/essential business data in case of a disaster or technical outage.
