可以与目标所有者和权限进行 Rsync 吗？

Question

源服务器有一个所有者，即 root。

----/home/sub1/test1 
----/home/sub2/test1

我的本地机器是目的地。

----/home/sub1/test1 owner by user1
----/home/sub2/test1 owner by user2

如何将新的更新文件从源服务器同步到本地计算机并且不更改本地所有者？

编辑

我需要在一个命令中同步所有源，因为有许多文件夹和本地计算机也有许多所有者。也许有可能吗？

谢谢。

听起来您不希望它们在转移后发生变化。

尝试以下命令：

rsync -avr -o -g /source/directory user@:destinationHost/destination/directory

如果不使用这些选项，用户和组将更改为接收端的调用用户。如果您想指定其他用户，则需要在脚本中添加 chown 命令。

-o, --owner
    This option causes rsync to set the owner of the destination file to be 
    the same as  the source file, but only if the receiving rsync is being run 
    as the super-user (see also the --super and --fake-super options). Without 
    this option, the owner of new and/or transferred files are set to the invoking 
    user on the receiving side...

-g, --group
    This option causes rsync to set the group of the destination file to be the same as 
    the source file. If the receiving program is not running as the super-user (or if
    --no-super was specified), only groups that the invoking user on the receiving side
    is a member of will be preserved. Without this option, the group is set to the default
    group of the invoking user on the receiving side...
