Re: [gentoo-user] rsync via ssh
I have done a similar thing at work, except what I do is first create an
ssh tunnel, then rsync to the locally listening port. Works perfectly.
In my setup the remote server is running an SSH server which is not
accessible directly. Maybe this will help you.
#!/bin/bash
SSL_COMMAND=ssh -p [EMAIL PROTECTED] -f -N -L 8000:localhost:873
SSL_PID=`ps aux | grep $SSL_COMMAND | egrep -v 'grep' | awk '{print $2}'`
if [ $SSL_PID == ]; then
echo = Creating SSH tunnel to myserver
$SSL_COMMAND
SSL_PID=`ps aux | grep $SSL_COMMAND | egrep -v 'grep' | awk
'{print $2}'`
else
echo = SSH tunnel already exists. Using existing tunnel.
fi
if [ $SSL_PID != ]; then
echo = Connecting through SSH tunnel with PID $SSL_PID
rsync rsync://localhost:8000/wwwroot
/mnt/samba/hotcopy/myserver/wwwroot \
-rvtzp --delete --modify-window=1
echo = Closing SSH tunnel
kill $SSL_PID
else
echo ERROR: SSH Connection failed! The backup could not complete
fi
Cheers,

Another responder suggested rdiff-backup. I'll give that a try first.
