Xtrabackup MySQL 备份工具
Xtrabackup是一个对InnoDB做数据备份的工具，支持在线热备份（备份时不影响数据读写），是商业备份工具InnoDB Hotbackup的一个很好的替代品。
Percona XtraBackup 2.3.7 发布了，主要更新如下：
新特性：
Percona XtraBackup 实现了一个新的 --remove-original 选项，一旦那些加密和压缩文件已被解密/解压，可以用于删除它们。
Bugs 修复：
XtraBackup was using username set for the server in a configuration file even if a different user was defined in the user’s configuration file. Bug fixed #1551706.
Incremental backups did not include xtrabackup_binlog_info and xtrabackup_galera_info files. Bug fixed #1643803.
Percona XtraBackup would fail to compile with -DWITH_DEBUG and -DWITH_SSL=system options. Bug fixed #1647551.
xtrabackup --move-back option did not always restore out-of-datadir tablespaces to their original directories. Bug fixed #1648322.
innobackupex and xtrabackup scripts were showing the password in the ps output when it was passed as a command line argument. Bug fixed #907280.
Incremental backup would fail with a path like ~/backup/inc_1 because xtrabackup didn’t properly expand tilde. Bug fixed #1642826.
Fixed missing dependency check for Perl Digest::MD5 in rpm packages. This will now require perl-MD5package to be installed from EPEL repositories on CentOS 5 and CentOS 6 (along with libev). Bug fixed #1644018.
Percona XtraBackup now supports -H, -h, -u and -p shortcuts for --hostname, --datadir, --userand --password respectively. Bugs fixed #1655438 and #1652044.
其他 bug 修复: #1655278
