[Eug-lug] rsync problems

[Ben Barrett]

Are you using the "--partial" option for rsync?
The best approach I've seen using rsync for backups uses a wrapper to
setup a lock-file of sorts,
kicked off [repeatedly] by a cron job... the wrapper script will not
try to do 2 rsyncs at once, in short.
Sticking with rsync for now... do you have any reasons other that
network timeouts to desire a different solution?

PS - you may also want to consider "--partial-dir" and
"--delay-updates" options... and have a wrapper script setup so that
you can confirm when the xfer is in fact complete.  Consider recording
changes via a versioning system on the receiving end, each time a
transfer is noted at complete.
