Duplicate folders posing backup challenges

Business Plus customer. We seeded Box a few years ago with FTP uploads from an old file server.

That Windows file server did not have and could not have had duplicate folders present. However, we're seeing them now on Box, on content clearly from that seed.

The problem we're experiencing is that we're trying to back-up our Box content once a quarter via FTP downloads to local storage (FileZilla). I'm performing folder syncs to capture new content and remove local content no longer present on Box. It was chugging along just fine, until FileZilla says it cannot continue because it cannot create duplicate folder names locally.

Upon investigation, every time this error comes up, sure enough there are duplicate folders on Box, with one of them often 0k in size. Everything comes to a halt while I navigate to the area in question and delete or rename the duplicate folder. Then, in Filezilla, I have to disconnect and reconnect the FTP session in order for a directory refresh to happen (it won't happen with a FileZilla refresh command).

With 30 terabytes of data, this is unworkable. I haven't found any vendors out there who do cloud-to-cloud backups for Box in an affordable manner. The only one that looks decent would cost more than our Box subscription itself!

So for now, we have to rely on FTP downloads to maintain a DR copy of our data. Not great, because even if we weren't experiencing hiccups due to dupllicate folders, it still takes a long time. Better than nothing.

Can Box run its own reports to discover duplicate folder names in the same directory? Then we could at least assign a team member with some capacity to clean all that up and then our FTP downloads can run without intervention.

I'm also wondering - have I not had enough coffee yet this morning, or did Box remove the ability for us to submit tickets? 

We are already starting to consider moving on from Box because of lock-in and irritations with the UI which make no sense. OneDrive isn't perfect, but we're already an E3 customer and there is a vibrant marketplace out there for keeping copies of our files safe in alternate locations.
