I can't imagine that being the case very often. Rsync does the 'compare between machines' is done in an extremely efficient way, so large files with small changes have only the small changes transferred. If you haven't tested rsync, I'd recommend trying it and measuring the bandwidth used. Or at least look through some of the theory at http://rsync.samba.org/documentation.html. > Add to that that a perl coder should need like 5 minutes to let the > backuppc extract tool use bzip2, and it becomes an interesting > alternative again, don't you agree? I haven't needed compression beyond what ssh -C provides badly enough to worry about it, but many of my files are pre-compressed anyway. -- Les Mikesell [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
