Zoker on "[Plugin: BackWPup - WordPress Backup Plugin] FTP upload hits 65% and jumps back to 0%"

Hi there,

I have a issue with the FTP upload:
The system shows 65% upload to ftp and then jump to 0% again.

On another wp installation, the upload to a ftp destination works fine (same destination/backwpup settings/webhosting package).

In the log, the system seems to reconnect to the ftp server every 20 seconds:

(I changed my domain to xyz in the screenshot)

Do you have any idea, why the systems does reconnect every 20 sec?
The upload does not stop, it just goes to 65% (is not every time 65%, but something like that) an jumps back to 0%

Thank you!
Zoker
