File Management: Removing of files from Server2 IF the same file is removed from Server1.

Hi Folks,

I have a requirement of file management on different servers.

Source Server is SERVER-A.

Two servers will fetch files from SERVER-A: SERVER1 and SERVER2.

4th SERVER is SERVER-B, It will fetch files from SERVER1. If SERVER1 goes DOWN, SERVER-B will fetch pending files from SERVER2(no duplicity).

Suppose, Server1 has 4 files file1/2/3/4 (It fetched it from SERVER-A) and SERVER2 also 4 files file1/2/3/4(it also fetched it from SERVER-A). There is no SYNC between SERVER1 and 2.

Now SERVER-B will fetch file1/2 from SERVER1 and it will delete same. So SERVER1 has now file3/4. SERVER1 goes down.
So SERVER-B will start picking file from SERVER2(SERVERB will be manually pointed to SERVER2), but it should only pick file3/4 as file1/2 were already picked.

I need a mechanism by using which - If SERVER-B deletes a file from SERVER1, then it also get deleted from SERVER2 - NOTE SERVER-B is not capable to do this, so this has to be done from SERVER1 end. If file1/2 is removed from SERVER1, then it should delete it from SERVER2.

Please let me know if more clarification is required.

I think, RSYNC is one of the way, but requirement is limited.

Thanks to all in advance.

       obus-gen-server [ options ] input-files

DESCRIPTION

       obus-gen-server	generates  an ocaml module from D-Bus introspection files. The generated module contains code for defining a D-Bus service

       -keep-common
