Hi all, I'm seeing network speeds at about 35-45 Mbps when using BackupPC and rsync over ssh.
Running iperf below I notice the network should theoretically be capable of a bit more than that. I understand that ssh adds quite a bit of bottleneck. [root@titan ~]# iperf -c cyndane ------------------------------------------------------------ Client connecting to cyndane, TCP port 5001 TCP window size: 42.5 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.8 port 51754 connected with 192.168.0.9 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 398 MBytes 334 Mbits/sec [root@titan ~]# Just to clarify, titan above is the BPC-server and has some local disk space where the backup pool is. Cyndane is the host being backed up. Both have gigabit-NIC's and a ditto switch between them. After reading one of the answers at <<http://serverfault.com/questions/377598/why-is-my-rsync-so-slow>>, I kinda' wonder if the NFS-angle would work for use with BackupPC and how I would go about it. Is the tar transfer method the only one supported by BPC if using NFS for example? Rsyncing a NFS-mounted remote host supposedly is a lot faster than doing rsync over ssh. Any thoughts on this? Has anybody on this list maybe set up their systems using NFS and can share their experience?
