   rsync    ( 1 )

быстрый, универсальный, удаленный (и локальный) инструмент для копирования файлов (a fast, versatile, remote (and local) file-copying tool)

SYMBOLIC LINKS

Three basic behaviors are possible when rsync encounters a symbolic link in the source directory.

By default, symbolic links are not transferred at all. A message "skipping non-regular" file is emitted for any symlinks that exist.

If --links is specified, then symlinks are recreated with the same target on the destination. Note that --archive implies --links.

If --copy-links is specified, then symlinks are "collapsed" by copying their referent, rather than the symlink.

Rsync can also distinguish "safe" and "unsafe" symbolic links. An example where this might be used is a web site mirror that wishes to ensure that the rsync module that is copied does not include symbolic links to /etc/passwd in the public section of the site. Using --copy-unsafe-links will cause any links to be copied as the file they point to on the destination. Using --safe-links will cause unsafe links to be omitted altogether. (Note that you must specify --links for --safe-links to have any effect.)

Symbolic links are considered unsafe if they are absolute symlinks (start with /), empty, or if they contain enough ".." components to ascend from the directory being copied.

Here's a summary of how the symlink options are interpreted. The list is in order of precedence, so if your combination of options isn't mentioned, use the first line that is a complete subset of your options:

--copy-links Turn all symlinks into normal files (leaving no symlinks for any other options to affect).

--links --copy-unsafe-links Turn all unsafe symlinks into files and duplicate all safe symlinks.

--copy-unsafe-links Turn all unsafe symlinks into files, noisily skip all safe symlinks.

--links --safe-links Duplicate safe symlinks and skip unsafe ones.

--links Duplicate all symlinks.
