It’s a little diffrent from normal SSH connection, so i post it as stand-alone howto. I use here [LAPTOPUSER] as client username, and has to be replaced in the commands.
Generate a public/private key on the server machine in /home/backuppc/.ssh/laptop & Generate a public/private key on the client machine in /home/$USER/.ssh/laptop. Replace [LAPTOPUSER]
sudo su backuppc cd ~ ssh-keygen -t dsa -f ~/.ssh/laptop2 scp ~/.ssh/laptop2.pub [LAPTOPUSER]@192.168.0.11:~/
Create the folder ‘.ssh’ if it doesn’t exist and configure the public key to OpenSSH’s liking. Replace [LAPTOPUSER]
ssh [LAPTOPUSER]@192.168.0.11 if [ ! -d .ssh ]; then mkdir .ssh ; chmod 700 .ssh ; fi ; mv laptop2.pub .ssh/ ; cd .ssh/ ; if [ ! -f authorized_keys ]; then touch authorized_keys ; chmod 600 authorized_keys ; fi ; cat laptop2.pub >> authorized_keys ; rm laptop2.pub; exit
Test if you can connect without being prompted for a password, but you should have to enter the passphrase
ssh -i ~/.ssh/laptop2 [LAPTOPUSER]@192.168.0.11
Manually Rsync via SSH
rsync -avrz $USER@laptop:/home/$USER/ -i ~/.ssh/laptop2
Now you need the ssh-agent,
but you will propably get the following error (with user backuppc):
Could not open a connection to your authentication agent.
then just use this command:
Edit backuppc settings:
rsyncclientcmd: replace root with [LAPTOPUSERNAME] and add -i ~/.ssh/laptop2
that should work and backup with your clients username
