If Ola is still around and her bulk-upload work is complete[1], maybe we can:
a. make a local instance of the backup,
b. bulk download the /storage directory with all contents, and then
c. bulk upload the file into openacs.org?

In either case, maybe the script could be generalized so that it is useful for more than just this one case.
