Elements and Performance Criteria

1. Review the database architecture to plan backup and recovery
   • Examine the architecture of a database file system
   • Determine the most appropriate methods for backup and recovery
   • Identify and examine the likely or possible risk and failure scenarios
   • Prepare a backup maintenance schedule
   • Prepare a contingency plan
2. Determine backup methods appropriate to database requirements
   • Evaluate the range of backup and restoration methods, based on organisational and security standards, and on the assessment of likely, or possible, failure scenarios
   • Complete full off-line backups according to organisational and security standards, with minimal down time
   • Complete online file backups, as determined by organisational and security standards, with minimal down time
   • Employ disk mirroring and redundant array of inexpensive disks (RAID) hard disk configurations to keep copies of files
   • Arrange off-site copies of backup files
3. Establish recovery points and disaster-recovery procedures
   • Determine database recovery points based on the backup arrangements, according to organisational guidelines
   • Test the restore process to ensure that the database can be restored to a given recovery point, with minimal down time
   • Complete the restoration of the database to the point of failure, without loss of committed transactions
4. Create and deploy a standby database
   • Create or set up a standby database, in order to meet organisational guidelines
   • Implement a standby database to support critical business functions
   • Prepare the documentation for a standby database
