Hey Scott, this may sound weird but have pretty much the same setup as you and we're finding the cause of our terrible backup speeds to be a problem with ssh speeds on centos.
We don't know why this is happening yet but are working on it. Also we're on centos 4.4. Anyway try it yourself and see what you come up with. On the mac server your backing up use an sftp program such as transmit and copy a file over sftp to your backup server. On a 100M switch were only getting copy speeds of 2MB/s. Same setup and machines only useing the ftp protocol were getting 10MB/s So something is balled up with openssh on centos i think Maybe see if that's your problem - Jamie On 5/1/07, Scott <[EMAIL PROTECTED]> wrote: > Greets. > > I'm giving BackupPC 3.0.0 a try on my home network.
