更新日誌：

New Options

--version

The --version option has been added to the xtrabackup binary for printing its version. Previously, the version was displayed only while executing the binary without arguments or performing a backup. Bug Fixed: #610614 (Alexey Kopytov).

Changes

As exporting tables should only be used with innodb-file-per-table set in the server, the variable is checked by xtr abackup when using the --export option. It will fail before applying the archived log without producing a potentially unusable backup. Bug Fixed: #758888 (Alexey Kopytov).

Bugs Fixed

When creating an InnoDB with its own tablespace after taking a full backup, if the log files have been flushed, taking an increHTTP://www.aliyun.com/zixun/aggregation/29845.html">mental backup based on that full one would not contain the ad ded table. This has been corrected by explicitly creating the tablespace before applying the delta files in such cases. Bug Fixed: #766607 (Alexey Kopytov). In some cases, innobackupex ignored the specified xtrabackup binary with the --ibbackup option. Bug Fixed: #729497 (Stewart Smith). Minor file descriptors leaks in error cases were fixed. Bug Fixed: #803718 (Stewart Smith).

Other Changes

Improvements and fixes on the XtraBackup Test Suite: #744303, #787966 (Alexey Kopytov) Improvements and fixes on pla tform-specific distribution: #785556 (Ignacio Nin) Improvements and fixes on the XtraBackup Documentation: #745185, #72133 9 (Rodrigo Gadea)

XtraBackup 是一個用來備份MySQL的InnoDB資料庫的開源工具。

例如執行增量備份的命令是：
