copy doesn't really 'sync' since files in the source tree that have been deleted aren't correspondingly deleted in the destination (and empty directories aren't 'pruned').

rsync is specifically geared to doing fast sync's by virtue of a delta algorithm (whereas copy only looks at the timestamp).

Other than the above though, copy would be a neat solution.

Ahh - perhaps I'm missing something here.

You say that the files are available on a Unix share - why not use the built in copy task to do the synchronize? It includes smarts to only copy when necessary:

From the Ant Manual, on Copy:

"Copies a file or Fileset to a new file or directory. Files are only copied if the source file is newer than the destination file, or when the destination file does not exist. However, you can explicitly overwrite files with the overwrite attribute."

I've been using this to "synch" directories and it works very quickly, only copying changed files.

Cheers,
Bevan.
