How to install RSync on Windows?​​​​​​​

How to install RSync portable version?

If you need to put RSync command line on a USB flash drive to synchronize directories, you need to install cwRync and get the following files: rsync.exe, cygwin1.dll and cygz.dll

This allows you to synchronize local directories.

Example: It synchronizes the directory "F: / my files" on the USB key to the folder :c:\usb"

rsync -r -v --size-only --chmod=ugo=rwX "/cygdrive/f/my file" "/cygdrive/c/usb"

It is recommended to use - size-only because the modified date of files in Windows is not always reliable. - chmod=ugo= rwX is important otherwise you cannot read the files in the destination (NTFS rights locked without this option)
