xtrabackup 遠程流備份腳本

一、xbstream 流，本地文件夾能夠本身建立，異地文件夾必須存在

 innobackupex --host=127.0.0.1  --post=3306 --stream=xbstream  --compress /root/backup/ | ssh root@192.168.56.15 "xbstream -x -C /tmp/"

二、xbstream 流，對端機器須要解壓並清理壓縮文件

192.168.56.15
xtrabackup --decompress --target-dir=/tmp/
find /tmp/ -name "*.qp" |xargs  rm -f

三、xbstream 流對端須要安裝軟件

3.1 xtrabackup

3.2 qpress-11-linux-x64.tar

四、腳本，週一全備，其它都是增備

[root@es1 chkpoint]# cat backup.sh
#!/bin/bash

[root@es1 chkpoint]# cat backup.sh 
LOCALDIR=/data/backup
CHECKPIONTDIR=$LOCALDIR/chkpoint
REMOTEDIR=/tmp/


WEEKDAY=`date +%u`
INTERVARNUM=`expr $WEEKDAY - 1`
TISHWEEKFULL=`date -d "$INTERVARNUM day ago" +%F`
TODAY=`date +%F`

ssh root@192.168.56.19 "mkdir -p /$REMOTEDIR/$TISHWEEKFULL"
ssh root@192.168.56.19 "mkdir -p /$REMOTEDIR/$TISHWEEKFULL/$TODAY"


if [ ! -f $CHECKPIONTDIR/xtrabackup_checkpoints ] ;then

echo "沒有lsn信息，開始一次全備"

innobackupex --host=127.0.0.1 --history  --post=3306 --stream=xbstream   --compress --extra-lsndir=$CHECKPIONTDIR  $LOCALDIR |ssh root@192.168.56.19 "xbstream -x -C /$REMOTEDIR/$TISHWEEKFULL/"
exit 1

五、tar 目前不支持增備，壓縮解壓須要注意，須要tar -xizvf  *.tar.gz
