The major impact of using checksums is that both the client and the server

From what I've seen, lzma/xz compression is slower than bzip2, but generally

Folks--
I'm working with an old system I set up to copy files from one local
directory to another. I was using rdist for this, but I would prefer
to shift it over to rsync.
The one thing I'm missing is the trivial ability to force the group
owernship of the destination files to a specific group.

The first question is that if there is any risk for such a big number of
files? should I divide them into groups and rsync them in parallel or in
serial? If yes, how many groups is better?
For that amount of data, you ought to use something simple and recursive,
like cp -rp. A

That way if a file is put on the source side, the cript will pick it up
and begin copying it. However, if the file is a few hundred MB, it might
take longer than 15 minutes to copy it.
