What kind of FTP server are you using?
Do the correct permissions to rename/remove files exist for the FTP user?
What happens if you manually go in and delete the .tmp file?

1. Our webhost
2. Yes
3. The same thing happens over.

I should also point out that we have several other 3CX instances backing up this way without issues. The only difference is that this one has considerably more recordings stored. (There is more than enough FTP space available though)
