-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X) -r, --recursive recurse into directories -l, --links copy symlinks as symlinks -p, --perms preserve permissions -t, --times preserve modification times -g, --group preserve group -o, --owner preserve owner (super-user only) -D same as --devices --specials --devices preserve device files (super-user only) --specials preserve special files -H, --hard-links preserve hard links -A, --acls preserve ACLs (implies -p) -X, --xattrs preserve extended attributes -P same as --partial --progress --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. 断点续传 --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/20180619/
