Problems solved by technology

[0005] Oracle synthetic backup itself provides a powerful backup and recovery strategy, but there are still quite a few problems in the backup and recovery strategy in reality, how to minimize the number of database failures, so as to maintain the maximum availability of the database; when the database is unavoidable After the ground fails, the recovery time is minimized, so that the recovery efficiency can be maximized; when the database fails, how to ensure that the data is lost as little as possible or not lost at all, so that the data has the greatest recoverability

Abstract

The invention discloses a database synthetic backup and mounting recovery method. The method comprises the steps of describing a synthetic backup principle; performing login registration; performing a backup process; performing conventional recovery; and performing mounting recovery. In synthetic backup, all backups are incremental backups except first full backup, so that a daily backup window is greatly shortened, the space occupied by daily backup is greatly reduced, and the time of backing up all data is greatly shortened; instant recovery can shorten recovery time to a minute level; and the problem of Oracle database backup is solved from the aspects of time, space, efficiency and security.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a database synthesis backup and mount restoration method. Background technique [0002] Oftentimes, the computer is so weak that any of the chips on the motherboard, motherboard circuits, memory, power supply, etc. cannot work normally, which will cause the computer system to malfunction. If the computer's hard disk is damaged, data will be lost and must be restored from a backup. System backup can indeed solve the problem of database backup. However, the system backup strategy considers backup and recovery issues from the perspective of hardware, which requires a price. Sometimes, the backup of the hardware cannot meet the actual needs at all. If you delete a table by mistake, but you want to restore it again, the backup of the database becomes more important. [0003] The Oracle database has developed a total of 11 stages, making it a unique database technol...
