Snapshot not sending files to the remote destination

It was working fine up until we updated your plugin and then rolled back to the older version. The latest version does not allow subdirectories so we rolled back to 3.0.4 and now the push of the file is failing.

I am getting a fail message when the snapshot plugin attempts to send the snapshot of a site to a FTP location. However, the FTP destination is able to connect and it successfully creates the subfolder, but the snapshot file is not being sent.
