When the master server suddenly fails or stops working due to other damages, it starts to start the VM that is synchronized with the master server and backed up, send an email to the administrator or send a notification directly to the mobile terminal of the Administrator. After the master server recovers, the VM includes the operating system, database, and application.ProgramAnd other related data are seamlessly migrated back to the original master server. To complete these operations, you only
The two problems are: whether the backup and recovery policies are secure, that is, whether the database can be backed up in a timely and accurate manner. The second is to consider the high efficiency of the DB2 data backup and recovery solution. If it takes several hours to back up or recover a DB2 database, the backup and recovery solution will be safe in a tim
The recovery model is designed to control transaction log maintenance. The recovery mode illustrates the risk of job loss. Can it be recovered at that time?
SQL Server databases have three recovery modes: simple recovery mode, full recovery mode, and large-capacity log

Some other maintenance activities are involved when using the recovery directory, such as upgrading the recovery directory during database upgrades or migrations, manually configuring the database counterpart, and synchronizing the recovery directory after some database operations.

the inconsistent translations of various technical documents, the specific concepts are different. In Oracle databases, three types of Database Backup are called full backup, differential incremental backup, and cumulative incremental backup. Incremental incremental is the Incremental backup we mentioned above, while incremental is the differential backup we mentioned above. In order to unify the text, the author still uses Differential backup and Incremental backup in the following explanation

Therefore, when the above fault occurs, we hope to re-establish a complete database, which is called database recovery.

This paper mainly describes how to improve the DB2 data backup and recovery efficiency of practical steps, in the design of data backup and recovery scenarios, we mainly consider two aspects of the problem.The first is whether the backup and recovery strategy itself is safe, that is, the timely and accurate completion of the database backup work.The second is to

When learning basic knowledge about Oracle, we will understand the concept of Instance Recovery or Crash recovery, sometimes even these two terms share the same meaning in our daily language. In fact, there is a difference between Instance Recovery and Crash Recovery: for the Recov
When the database needs to recover the media, in order to ensure that the database can smoothly perform the recovery process, restore the database to the current state. All we need to do is verify! What is verification? Of course, it is to verify whether the backup set and archive can be effectively restored. After the restore is prevented, when executing the recover operation, we find that the archive is missing and suddenly dumb.
For example, we hav
