What is the backup and recovery strategy in DB2?

The backup and recovery strategy in DB2 includes the following aspects:

1. Regular backups: Regularly back up the database to ensure the security and recoverability of the data.
2. Differential backup: In addition to full backup, differential backup can be done regularly, which only backs up the data that has changed since the last full backup, reducing backup time and storage space consumption.
3. Log backup: Back up the database transaction logs to ensure that recovery operations can be performed by replaying the logs in case of a database failure.
4. Regularly conduct recovery tests to verify the integrity and availability of backup data, ensuring that operations can run smoothly when data recovery is truly needed.
5. Backup strategy monitoring: monitor the execution and results of backup operations to promptly identify any failures or abnormalities, adjust strategies accordingly, and take necessary actions.

By implementing the above backup and recovery strategy, it is possible to effectively ensure the security and reliability of the database, ensuring that data can be recovered promptly in the event of a disaster.
