synchronization attachment folder Master/slave server

hello all,

I have 3 server and I install redmine on all my server and I synchronized my database using PAF.

I want to get clear replica of server1 on my server2 and server3

I copied all files from server1 (/default/files/) to server2 and 3 are stupid idea.

Is there any possibility to synchronize /var/lib/redmine/default/files/,plugins, themes and images to my new servers.

Thank you

Redmine
