I have been working hard to try to fix why I have not got the ubuntu client to urbackup to work. After many expriment, I came to the following, which solved many problems.
urbackupServer
Settings / File Backups / Default Folders to Save: -x -f -d /boot -n boot
Client ubuntu
sudo uninstall_urbackupclient
rm -Rf /usr/local/var/urbackup
sudo rm /usr/local/var/urbackup/server_idents.txt
sudo apt-key adv --recv-keys --keyserver keys.fedoraproject.org 370C85D709D26407
echo “deb [arch=amd64] https://cpkg.datto.com/datto-deb/public/$(lsb_release -sc) $(lsb_release -sc) main” | sudo tee /etc/apt/sources.list.d/datto-linux-agent.list
sudo apt-get update
sudo apt-get install dattobd-dkms dattobd-utils
sudo su
TF=mktemp
&& wget “https://hndl.urbackup.org/Client/2.2.5/UrBackup%20Client%20Linux%202.2.5.sh” -O $TF && sh $TF; rm $TF
sudo apt install -f
If you get three choices as well, option 1.
sudo urbackupclientctl add-backupdir -x -f -d /boot -n boot
Tips:
((sudo apt-get remove --purge urbackup-server))
sudo urbackupclientctl start --full --client 192.168.1.1XX (<–IPClient)
sudo urbackupclientbackend -i -v debug
sudo urbackupclientctl list-backupdirs
sudo urbackupclientctl add-backupdir -d /boot
