Ansible Sync Remote Server A to Remote Server B

Assuming the target (inventory_hostname) is A, the copy target is B and the controller is C.

Most solutions you’ll have found won’t work with become: yes, you can only use become on the target server, but no the ‘other server’, so using things like rsync+ssh://user@B:/home/ (where user is not root) won’t work. Even though that is probably the most common solution for sync from A to B while controller is C.

Delegation just changes the ‘target’ and which means that your play instead of doing a sync from C to A does C to B. There is no existing solution with the synchronize action that will handle a 3 way + become. You can at best do sync A to C and then C to B within a playbook.

Other alternatives:

  • Install and run rsync server (runs as root) on B and use synchronize from A with dest: rsync://user@B:/home
  • Setup /home as network share (if NFS, no root squash) and use synchronize with ‘local paths’
  • Enable a root login from A to B and then dest: rsync+ssh://B:/home
