Links

SyncDat will attempt to copy symbolic links between unix systems.  The link target will be copied exactly.

If the server or remote account has been configured with the RestrictHome option enabled, then SyncDat will not be permitted to create or modify symbolic links on the server.

Different platforms have different rules for the handling of modification dates, id numbers, and access modes on symbolic links.  As a result, this meta data may not be precisely preserved.  SyncDat will update links based on comparisons of the actual target path.

Windows ShortCuts, also known as shell links, are regular files with a ".lnk" extension.  As such, they will be copied just like any other file.  Windows symbolic links are not preserved.

macOS Aliases store their information in the resource fork of the file, usually leaving a zero sized data fork.  macOS specific meta data is not preserved, so Aliases will also not be preserved.  macOS symbolic links are preserved just as for unix symbolic links.

Unix hard-links are treated like copies of the target file.  The data will be duplicated for each hard-link.
