 * We’d like to use CDN with Origin Push and keep media on a separate machine. We’ve
   exported the media library. However, once a file has been pushed, it cannot be
   pushed again.
 * Do you plan to allow updates to media library assets to be pushed with the ftp
   tool?
 * Thanks.

 * It’s an expensive operation to check all attachments for changes at any interval.
   Yes it’s a possibility, but for now if you update old attachments you have to
   manually do an another export.

 * There is another way of looking at this. I just noticed that a change in file
   size is picked up by w3tc, and the file is resent – nice!
 * Each file to be sent is checked on the remote server with ftp_size and if found
   and the size matches, the “File already exists” message is displayed, otherwise
   the file is resent.
 * It would be extremely helpful to add support for a date check with ftp_mtdm (
   if the remote server supports it).
 * If ftp_mtdm is not an option, because not all servers support it, a simple time
   stamp of the last transfer (includes, theme, custom, etc.) stored in the config
   could be used to check files on the way out.

 * Frederick – I’ve added a little code to our copy of [http://Ftp.php](http://Ftp.php)
   that checks file dates (if available) before deciding that a file already exists.
   Works great.
 * I’ll send it or publish here if you want it.

 * Is it possible to not use FTP but instead use something else, like rsync, to 
   keep files in sync? I think this would be better, less intensive, no?

 * We cannot assume that a given server (and PHP permissions) would have rsync installed
   and allow rsync to be used, nor that the system user running it has sufficient
   privileges even if it did work in every single case.

 * ok, thanks. I can handle the rsync. Perhaps all I need is a way to rewrite media
   URLs so the external server is used.

 * I am working on an auto-(re)upload feature, but the problem with it is that not
   every server supports all of the same functionality.
