MYSQL-NC+ xtrabackup 备份到远程

NC+ xtrabackup 备份到远程：

source:192.168.30.36
target 192.168.9.104

1:开启目标库nc 监听

target:
nc -l 9999 | tee >(sha1sum > destination_checksum) > /data/backup/backup.xbstream

2：源库传备份，亲测不落地

source:
xtrabackup --defaults-file=/data/db/mysql3366/my.cnf --user=root \
--password='XXX' \
--use-memory=8G --parallel=4 --backup \
--stream=xbstream --target-dir=./ | tee >(sha1sum > source_checksum)| nc 192.168.9.104 9999

3:解压

xbstream -x < backup.xbstream -C ./

4:恢复：

xtrabackup --defaults-file=/data/db/mysql3366/my.cnf --prepare --target-dir=/data/backup 
xtrabackup --defaults-file=/data/db/mysql3366/my.cnf --datadir=/data/db/mysql3366/data/ --copy-back --target-dir=/data/backup/
