I need to backup files with various attributes from a client to a server (both on LM19.3). One of the solutions which preserves their source attributes is to run rsync over ssh, something like that:
Code: Select all
rsync -a --rsync-path="sudo rsync" -e ssh /media/user1/source user2@server:/media/user2/destination/
However for this to work as expected, rsync needs also to be added to sudoer list as NOPASSWD on the server side:
This setup makes backing up with attribute preservation work fine. But how secure it is to have a passwordless rsync on the server? Is it inviting problems? Or I'm thinking too much? Our main concern is unauthorised copying of sensitive data. Clearly if you can
you can send any file from the server to an arbitrary internet location.
What are your thoughts?
