mysqlblasy 介绍
MysqLblasy 是一个为懒惰的系统管理员编写的 MysqL 备份工具，是一个 Perl 脚本，实现了自动的静默的 MysqL 备份。

* backup rotation to avoid disc overflow * dump some or all databases from a database instance * compress dumps (using gzip,bzip2,zip,tar) * optimize tables * syslog facility (only on unix-like system, not win32) * unix style output (loglevels, errors to stderr) * security: no shell on external commands! * NO root privileges required * NO external dependencies except Perl and MysqL * designed for automation (for example cron)
