rolls back the data that has been modified but not committed.2. Xtrabackup remembers log sequence number (LSN) at startup, and copies all data files. The copy process takes some time, so if the data file changes during this period, the database will be at a different point in time. At this point, Xtrabackup runs a background process that monitors the transaction log and copies the latest modifications from the transaction log. Xtrabackup must continue to do this because the transaction log is r

If you want to use file system backup to back up the database, the same problem also occurs: If the database table is modified during File system backup, when you enter the inconsistent subject status of the backup
The ORACLE tutorial is backup and recovery of the Oracle database. ---- When we use a database, we always hope that the content of the database is reliable and correct. However, due to computer system faults (including machine faults, media faults, and misoperations ), databases may also be damaged, so it is imperative to restore data as soon as possible. If the database is backed up at ordinary times, it i

There are three methods for ORACLE backup and recovery:
(1) Data Pump (expdp/impdp)
(2) Cold backup
(3) RMAN backup
In terms of classification, (1) and (2) are collectively referred to as "cold" backup and (3) as "hot" backup.

A hot backup is a copy of a data file when it is in use. During the replication process, DBWR is also in progress, so backups may receive some "inconsistent" backups:
Some data blocks may be older than the other blocks
The SCN of some blocks may be earlier than the SCN on the head of the data file
Some blocks may contain a partial update of the redo record, and other parts may be on the data file or on other data files

Data backed up using this method is best restored to the same version of the server, and different versions may not be compatible. In the recovery, you can directly copy the backup files to the MySQL data directory to achieve the restoration. When you restore th

Oracle Clusterware puts the entire cluster's configuration information on shared storage, which includes a list of cluster nodes, a cluster database instance to a node map, and CRS application resource information. It is also stored on an OCR disk (or OCFS file). Therefore, the importance of this configuration file is self-evident. Any action that makes an OCR configuration change is recommended to back up OCR immediately between operations or after. This paper is mainly based on Oracle 10g RAC
