Have you resolved this problem? We are experiencing the same. We are using 2.7.1+. Full restoring fails at +- 27%. If we backup just the Question Bank, backup process freezes. File not large, about 45Mb, however we have about 400 questions in the bank for this course with grading data. We need to migrate this course to another server and tearing our hair out.
