When you run rsync/rsyncd, the client sends it's entire directory listing first, then the backuppc server wades through its last full making the comparisons. Unless a lot of files have changed, this won't take much bandwidth but is still a lot of work. You might look at the --checksum-seed option to reduce the computation. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
