MYSQL备份，每天全量备份（排除由于GTID的缘故造成恢复问题的系统库），然后通过Gzip进行压缩。

#有些时候，我们要对数据库进行备份的时候，由于GTID的缘故，导出系统库后，再次导入其他环境的数据库时，就会出问题。所以，我们需要排掉一些系统库，排除GTID对于数据库迁移的影响。db=`$mycmd -e "show databases;"|grep -Evw "Database|information_schema|performance_schema|test|mysql|sys"`
${DUMP_InnoDB} --databases $db --ignore-table=要忽略的表 |gzip > $BACKUPPATH/$BACKUPDATE/full_$(date +%w).sql.gz#flush logs
$mycmd -e 'flush logs'
解压缩方法：使用gunzip gunzip full_2.sql.gz
