--partial
By default, rsync will delete any partially transferred file if the transfer is interrupted. In some circum‐
stances it is more desirable to keep partially transferred files. Using the --partial option tells rsync to keep
the partial file which should make a subsequent transfer of the rest of the file much faster.

--progress
This option tells rsync to print information showing the progress of the transfer. This gives a bored user some‐
thing to watch. With a modern rsync this is the same as specifying --info=flist2,name,progress, but any
user-supplied settings for those info flags takes precedence (e.g. "--info=flist0 --progress").
显示传输进度 -v, --verbose
This option increases the amount of information the daemon logs during its startup phase. After the client con‐
nects, the daemon’s verbosity level will be controlled by the options that the client used and the "max ver‐
bosity" setting in the module’s config section.
输出详细信息 --delete
This tells rsync to delete extraneous files from the receiving side (ones that aren’t on the sending side), but
only for the directories that are being synchronized. 推荐用法：
rsync -aP --delete . /tmp/20180619/
rsync -av --delete --progress . /tmp//
[root@prdweb02 ~]# ll | grep tes

源目录后加/则只会把这个目录下的内容复制过去
[root@prdweb02 ~]# rsync -aP --delete test_compose/ /tmp/20180619/
源目录后不加/则会把这个目录本身也复制过去
[root@prdweb02 ~]# rsync -aP --delete test_compose /tmp/20180619/
