Backup and Recovery
In fact, backup and recovery is one of the most important duties if a DBA. Yet, so many DBAs often found themselves in last-gasp efforts, escalating a call to Oracle Worldwide support for a severity-one database down issue. To survive such a scenario, a DBA is expected to:
- plan his backup strategies and test all disaster recovery procedures.
- trying out different database crash and recovery scenarios before production migration.
- document backup and recovery strategies.
In some situations the customer may event have a penalty clause in their contract: "IF THE DATABASE IS DOWN FOR TWO HOURS OR MORE, THE CONSULTING ORGANIZATION IS LIABLE FOR X AMOUNT OF DOLLARS FOR EVERY ONE HOUR SUBSEQUENT DOWN TIME".
