Linux 下的文件同步,rsync真的好用!

因为我的MacUbuntu都自带这个rsync了,不必自己装,想装的可以去官网,开源软件:开源地址,也有Windows下的实现。

rsync is a file transfer program capable of efficient remote update
via a fast differencing algorithm.

Usage: rsync [OPTION]... SRC [SRC]... DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
or rsync [OPTION]... [USER@]HOST:SRC [DEST]
or rsync [OPTION]... [USER@]HOST::SRC [DEST]
or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.

--specials preserve special files
-D same as --devices --specials
-t, --times preserve times
-O, --omit-dir-times omit directories when preserving times
--super receiver attempts super-user activities
-S, --sparse handle sparse files efficiently
-n, --dry-run show what would have been transferred
-W, --whole-file copy files whole (without rsync algorithm)
-x, --one-file-system don't cross filesystem boundaries

--existing skip creating new files on receiver
--ignore-existing skip updating files that already exist on receiver
--remove-source-files sender removes synchronized files (non-dirs)
--del an alias for --delete-during
--delete delete extraneous files from destination dirs
--delete-before receiver deletes before transfer (default)
--delete-during receiver deletes during transfer, not before

--max-size=SIZE don't transfer any file larger than SIZE
--min-size=SIZE don't transfer any file smaller than SIZE
--partial keep partially transferred files
--partial-dir=DIR put a partially transferred file into DIR
--delay-updates put all updated files into place at transfer's end
-m, --prune-empty-dirs prune empty directory chains from the file-list
--numeric-ids don't map uid/gid values by user/group name
--timeout=TIME set I/O timeout in seconds
-I, --ignore-times don't skip files that match in size and mod-time
--size-only skip files that match in size

服务端和客户端的模式要配置大量的信息,下次用到再说吧,这次就用简单的 ssh 模式。

把自己的电脑暴露在公网不太好,找自己的小米手机做了个中转,因为我的登录密码实在太简单了可是我又不想改

首先需要把自己的文件同步到中转端:

1
rsync -auv -e "ssh -i ~/Documents/common/key/mi" --progress /Users/onns/Documents/common android@xm.onns.xyz:/home/android/

为了方便能在任何位置使用命令,建议所有的文件/文件夹都是绝对路径。

注意一下-e参数,因为服务器设置了密钥体系,所以这个-e的参数其实是在告诉rsync怎么连服务器,等价于:

1
ssh android@xm.onns.xyz -i /Users/onns/mi

平时ssh加密钥的时候都是-i参数。

$ rsync -auv -e "ssh -i ~/Documents/common/key/mi" --progress /Users/onns/Documents/common android@xm.onns.xyz:/home/android/
building file list ...
196 files to consider

sent 4488 bytes received 20 bytes 3005.33 bytes/sec
total size is 719894 speedup is 159.69

同样地,远程再拉取一下中转端的数据就好了:

1
rsync -auv -e "ssh -i ~/Documents/common/key/mi" --progress android@xm.onns.xyz:/home/android/common ~/Documents/

还有一个需要注意的事情是,类似cpmv一样,from端是要指明当前目录的,但是to目录只需要指明你想要放的目录的上一级目录即可。看不懂,拷贝一次就理解了!
