mysqldump -uroot -p** -A -B -F --master-data=2 --single-transaction --events > /root/all.sql

恢復：

mysql -uroot -pVaren2100* < /root/all.sql

利用binlog日誌進行增量恢復

利用位置恢復：

mysqlbinlog --start-position="154" --stop-position="789694" /var/lib/mysql/mysql-bin.000002 | mysql -uroot -pVaren2100*

bin-log指定恢復數據庫

分庫備份：

#!/bin/sh

BACKPATH=/root/gool/backup

MYUSER=root

MYPASS=gool

MYCMD="mysql -u$MYUSER -p$MYPASS"

MYDUMP="mysqldump -u$MYUSER -p$MYPASS -x -B -F -R"

[ ! -d $BACKPATH ] && mkdir -p $BACKPATH

DBLIST=`$MYCMD -e "show databases;"|sed 1d|egrep -v "_schema|mysql|sys"`

for dbname in $DBLIST

do

$MYDUMP $dbname|gzip > /root/gool/backup/${dbname}_$(date +%F).sql.gz

done

分庫分表備份：

$MYDUMP $dbname $tablename |gzip > $BACKPATH/${dbname}/${tablename}_$(date +%F).sql.gz
