The backup file with the tilde is, in fact, *not* being saved in these situations where the corruption occurs. If it were, my students wouldn't be getting so upset. I think that the OS isn't allowing any saves (backup or otherwise) because of the user being over disk quotas, and RR isn't handling that gracefully. BTW, we're using xinet on a Sun sparc station to emulate a Mac file server. Most likely it's a problem with the communication between application/OS/file server software.
