Confused about TrueCloud Backup

I’m a bit confused as to how the TrueCloud Backup feature is supposed to work.
I created a trial account at Storj, created an access key+secret and set up a “TrueCloud Backup task” in TrueNAS. I selected my folder and inserted the keys and the task was set up successfully:

Path: /mnt/data/test
Credentials: Storj
Bucket: test
Folder: testfolder
Keep Last: 1
Transfer Setting: Default

The task is running successfully.
When I go to Storj I can see the “test” bucket, it also contains the “testfolder” folder, but “testfolder” does not contain my files, but contains the following:

data (directory)
index (directory)
keys (directory)
snapshots (directory)
config (file)

I figured there might be some metadata and my actual files would reside in “data”, but I can’t find my files there either.

So where are my files?
