依据列表文件拷贝

--files-from 从列表（一行一个文件路径）文件拷贝

1
rsync -a --files-from=/tmp/foo /usr remote:/backup

使用 ssh 协议传输

-e 来指定传输协议

-e ssh 指定 ssh 协议

1

--include --exclude 包含和排除要转移的文件

1
2
# include those files and directory only which starts with ‘R’ and exclude all other files and directory.
rsync -avze ssh --include 'R*' --exclude '*' root@192.168.0.141:/var/lib/rpm/ /root/rpm

设置文件大小的条件

1
2
# in this example, the Max file size is 200k, so this command will transfer only those files which are equal to or smaller than 200k.
rsync -avzhe ssh --max-size='200k' /var/lib/rpm/ root@192.168.0.151:/root/tmprpm

模拟运行，不产生实际效果 –dry-run

rsync --dry-run --remove-source-files -zvh backup.tar.gz root@192.168.0.151:/tmp/backups/
