XtraBackup 是一个用来备份 MySQL 的 InnoDB 数据库的开源工具。
Percona XtraBackup 2.2.6 发布,此版本现已提供在下载页面和Percona 软件库。此版本支持 Ubuntu 14.10 和 CentOS7。
更新内容如下:
新特性
Percona XtraBackup now reads server options from
SHOW VARIABLES
rather thanmy.cnf
configuration file.Percona XtraBackup now has more verbose output during initial table scan (it will now print a diagnostic message before performing a tablespace scan, which may take a long time on systems with large numbers of tablespaces) and before starting a backup/apply-log/copy-back operation in innobackupex (it will now print a diagnostic message with a timestamp to make it easier for users to get duration of the operation.)
Bugs 修复:
innobackupex didn’t take the default
datadir
, which caused backups to fail if thedatadir
wasn’t specified in themy.cnf
configuration file. Bug fixed #936934.innobackupex will now fail with an error when innobackupex –slave-info is used on a multi-threaded non-GTID slave, because
Exec_Master_Log_Pos
cannot be trusted for a multi-threaded slave. Bug fixed #1372679.InnoDB log scanning failure (bug #60788) would cause backups to fail. Fixed by porting the fix from MySQL 5.7. Bug fixed #1375383.
Options
--apply-log
and--decompress
weren’t marked as mutually exclusive, ie. if they were both specified, only--decompress
would work, which could lead to MySQL instance being started with an unprepared backup. Fixed by making mutually exclusive categories of options: 1.--decompress
,--decrypt
; 2.--copy-back
; 3.--move-back
; 4.--apply-log
. Bug fixed #1376874.innobackupex wasn’t creating directories specified in
innodb_data_home_dir
andinnodb_log_group_home_dir
when--copy-back
option was used. Bug fixed #1382347.Percona XtraBackup now supports all option modifiers supported by upstream MySQL: skip, disable, enable, maximum, loose. Bug fixed #664128.
Percona XtraBackup would fail to perform a full backup on Percona Server 5.5 if
innodb_log_file_size
variable wasn’t set in the[mysqld]
section ofmy.cnf
. Bug fixed #1334062.
其他 bug 修复:#1379905, #1386013, #1072695, #1375241, #1182841 和 #1343722.
