linux下的数据备份rsync同步

格式成NTFS的64G盘插到USB上然后sudo fdisk -l

Partition table entries are not in disk order.

安装NTFS支持包sudo apt-get install ntfs-3g
挂在u盘sudo mount -t auto /dev/sda /media

cd /media
mkdir backup
sudo apt-get install rsync
rsync -av --delete /home/pi/work/ /media/backup/

可以放到计划任务中去,定时刷新同步

也可以免密码同步
rsync -av --delete /home/pi/test user@network:/home/user/backup/
