When the directory /data doesn't exist in the backup Pod, it logs:

Does the backup generally fail or is this "just" a cosmetic error with the stack trace?

[tobru]

The backup doesn't fail, but I don't know the implications of this message. Not sure for what feature "can't list mounted folders for stats" stands for.
