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
server. The direct copy method is performed outside the server, and you must take measures to ensure that no customer is modifying the table you will copy. 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
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.

1 Xtrabackup can only back up the tables of InnoDB and xtradb two engines, but not the MyISAM engine's tables;
The 2 Innobackupex is a xtrabackup perl script that supports simultaneous backup of both InnoDB and MyISAM, but requires a global read lock for MyISAM backups. And there's the MyISAM. Incremental backups are not supported.

Today, we will mainly describe the correct steps for backing up and recovering DB2 partitioned databases, we use examples to illustrate how to correctly operate a DB2 partitioned database that has enabled the rollback and recovery mode, and use commands such as BACKUP, RESTORE, and ROLLFORWARD to back up data.
Restore and roll-forward operations with the OVERFLOW option. For the partitioned database of DB2,
