ODB lost?

I'm new to ObjectDB. While debugging small programs in single-step mode in NetBeans, the ODB appears to get corrupted or lost if I don't invoke close on EntityManager. If I re-run my program and get a new EntityManager, the instance behaves as if the data that was persisting is somehow gone. I noticed in the file system, indeed, the .odb file is gone, but there are <name>_<v>.odb files where <name> is the name of my odb and <v> is apparently a version number. Is there any way to recover <name>.odb? ... the name of my odb and <v> is apparently a version number. Is there any way to recover <name>.odb? ...
