Now you may be in the situation that you want to keep two directories in sync. In my example it was a virtual Fedora that I wanted keep a copy of in another place. My virtual is running on my home laptop and the work I do here I want to copy to a network connected drive out on the university.
Luckely one good hearted soul invented lsyncd. See github for more details and the manual.
What I did was to install lsyncd, which is a part of one of the Fedora repositories I have installed, in fact the default Fedora repository.
So, as root, issue:
dnf install lsyncd
then enable the lsyncd daemon
systemctl enable lsyncd.service
next edit the configuration file
sync{ default.rsyncssh, source="/home/klaus/workspaces", host="klaus@192.168.0.183", targetdir="/home/klaus/mounts/au-herning/m/mounts/uni/2016/E3ISD1/workspaces" }
From this you can see that I want to copy whatever exists in /home/klaus/workspaces to my laptop, identified by the login name and the IP address. The destination is my sshFS mounted remote filesystem on the university network.
Just before starting the lsyncd do ensure that your root account can login on the remote computer by issuing
ssh-copy-id -i ~/.ssh/id_rsa.pub klaus@192.168.0.183
test that you can login without using password.
Finally let the daemon loose
systemctl start lsyncd.service
In a few seconds you'll wee that the local directory structur and files are rsync'ed to the remote destination. Take a look on the man page for rsync - it's a pretty neat tool for synchronising computers and other stuff. lsync just builds an easy interface for using rsync.
