Ubuntu – Run rsync with root permission on remote machine

rsyncsudoUbuntu

I want to sync a folder from my machine with a folder on a remote machine. The remote folder can only be manipulated by root. I have an account on the remote machine which can use sudo. How can I run rsync such that it has root permissions on the remote machine?

I've tried the following:

rsync -avz -e ssh /home/ubuntu/my/lovely/folder ubuntu@x.x.x.x:/remote/lovely/folder --delete --rsync-path="sudo rsync"

But (after entering my password) I get the following error:

sudo: no tty present and no askpass program specified

Try this solution. In your sudoers file (/etc/sudoers) setup your user like this:

username ALL= NOPASSWD:/usr/bin/rsync

the NOPASSWD:/usr/bin/rsync tells sudo that when your user runs /usr/bin/rsync or just rsync that no password is needed.

Then your original --rsync-path="sudo rsync" should work.
