Okay thanks, but FYI I didn't have this problem with your older version...

I'll file support request with host (sigh).

It has to do with the file permissions or ownership on your server. The backup plugin creates files as whatever user PHP acts as, and it may be that your FTP user doesn't have permission to modify the PHP user's files, although that would be unusual.

Since this is a problem particular to a given server configuration, you should ask your host about it.

Any tips on how to delete backups which end up on server after using your plugin? Apparently the file and folder your software creates has some kind of tricky setting that doesn't let one just go in there with FTP and get rid of it... why is that, and how does one go about getting rid of the pesky things?

Thanks for any help.
