To my knowledge rsyncd is the rsync daemon process that runs in the
background. They are two parts of the whole, not two seperate animals.
Rsync is by far the safest and the smartest way to go about it. But
you're right, ssh adds a considerable amount of overhead.
Faster? Are you running 100MB NICs? Using switches instead of hubs?
Have decent quality Cat5 or Cat5e wiring your network together? Are the
wires running accross any high RF sources such as neon lighting or high
voltage lines of some kind?
Guess if I was going to troubleshoot speed, I'd start there. After
that, I dunno. You could do dedicated VPN tunnels from client to server
and then dump the contents of your backups to a share on the server
using NFS. You could do it minus the VPN part but NFS transmits
completely in the clear as I understand it. Not good.
I'm totally grasping at straws. This is something of a necessary evil
that I've come to accept I guess. Other things to look for - are you
certain that somethings simply not hanging on executing the backups or
are these very full machines you're backing up?
Dunno if any of that helps.

Hi,
I'm using backuppc on a local network. I'm currently using ssh and
rsync but I don't think it is fast enough, at least for the full
backups. I'm not quite sure where the bottleneck is (server, network,
ssh, rsync, tar, gz, etc).
For now I'll assume it's my ssh/rsync setup. I want to know how I can
speed this up.
What is the fastest solution for backuppc? Obviously SSH adds some
overhead. I want to use a very fast cipher. Something to just scramble
the data to give really basic privacy from packet snoopers. Any
suggestions???
What about rsync? My understanding is it is good for low bandwidth
networks but is it overkill for high bandwidth networks
(100Mbps/1000Mbps)?? The man pages suggest it is a more efficient
replacement for "cp" which suggests it would be good for high bandwidth
networks too.
Is rsyncd faster than ssh/rsh/rsync ???
Thanks for any help or pointers on how to backup large amounts (40GB+)
of data in the fastest possible time.
Cheers,
Brendan.
