We have already implemented such a feature. Basically, the client machine
creates an ssh tunnel to connect, and then executes a command on the server
to start the backup. Authentication takes place using a public/private key.
Here is the script used on the client machine:
#!/bin/sh
USERNAME=backuppc
PC=pc_name
PORT=22000
ssh -l support -R $PORT:localhost:22 backup.host.name backup.sh $PC
$USERNAME
The $PORT value is unique to each host and used in the client configuration
file as the port to use for ssh
and here is the script backup.sh used on the server:
#!/bin/sh
PC=$1
USER=$2
sudo -u backuppc /usr/local/bin/backup.sh $PC $USER
A similar script can be organised on windows using putty.
I don't think this is a "dirty hack", there is no other option than to have
rsync installed on the client machine.
I hope that helps
R.
