1,gzip+scp+gunzip
server1压缩并传送:

server1$ gzip -c /backup/mydb/mytable.MYD > mytable.MYD.gz
server1$ scp mytable.MYD.gz root@server2:/var/lib/myql/mydb/

server2解压:

server2$ gunzip /var/lib/mysql/mydb/mytable.MYD.gz

2,通道+ssh
server1压缩通过通道ssh传送到server2并在server2上解压

server1$ gzip -c /backup/mydb/mytable.MYD | ssh root@server2 "gunzip -c - > /var/lib/mysql/mydb/mytable.MYD"

3,通道+netcat
server2监听12345端口:

server2$ nc -l -p 12345 | tar xvzf -

server1传送数据:

server1$ tar cvzf - /var/lib/mysql/mydb/mytable.MYD | nc -q 1 server2 12345

4,rsync

server1$ rsync -ave ssh server2:/var/lib/mysql/mydb/ /home/mydb/

速度对比：
100 Mb/S Ethernet LAN.文件大小为738 MB可压缩至100 MB
