Issues with FTP Backup

Hello, I'm having an issue with the FTP backup storage.
I've been using a java software for my backups and this has been working fine. I've taken a few backups, however, on the first backup where it has needed to delete the grandfather backup (I believe) it has thrown this error:
Code:

I was wondering if anyone could shed any light on this? I'm rather stumped, I'd like to know if there is any way to prevent this from occurring in future.
