In principle it was supposed to work without needing the catalog. It looks like at some point I wasn't thinking through all the consequences and added code to ensure that the SD updated the catalog with the read statistics, so I imagine that is what is going on. On thing that you might try is to add the Volume name(s) to the catalog by doing an add command before running the restore. The correct solution is for the SD during a restore to attempt to read the Volume data from the catalog, but instead of failing when the data is not there, it should complain and continue. > > The test is to save to a mounted file (Windows share) system.
