Transfer only different and new files

[tnkk33]

I need (would like very much to have) a FileZilla extension that copies only new and changed files from local to server. It would have to work like this:

• Generate a hash code for each file in my local folder, and put the results in a file.
  
  Compare those hash codes to the existing file of hash codes that is on the server.
  
  Derive from that a list of files that are either (a) different, or (b) exist in the local folder but not on the server.
  
  Transfer only those files to the server, along with the current version of the hash code file.

Is this currently possible in FZ? It's obviously a little more involved that the simple "overwrite if..." options offered by FZ.

If not currently available in FZ, does anybody have any ideas about how to accomplish the steps mentioned above?

Thanks.

No, and I doubt it will ever be.

Either do the steps manually, using third-party software. FileZilla can aid in transferring the actual files you manually selected. For an automated solution, you might better look for a specialized backup/sync client with online capabilities. Maybe even a more modern transfer protocol, FTP is not really suited for that kind of task.

Thanks very much for the reply, Boco. Not what I wanted to hear, of course, but clear and precise and no-nonsense. I will pursue other options.

Thanks again.
