rsync 实现断点续传

Linux 主机之间即时传送文件，scp命令大家都很熟悉
但当要传送的文件较大，过程中如果网络中断了，就比较悲剧了。这时候可以考虑使用rsync命令替代scp，实现断点续传文件。

试验：rsync使用

环境：2台RHEL 5.7

需求：主机A传送文件夹TestDB到主机B

rsync -rP --rsh=ssh /home/oracle/TestDB/ oracle@192.168.1.173:/home/oracle/TestDB

实验rsync断点续传的过程记录：

[oracle@rac1-server TestDB]$ rsync -rP --rsh=ssh /home/oracle/TestDB/ oracle@192.168.1.173:/home/oracle/TestDB
