An organization which shall remain nameless insists on sending us TK50 data tapes in VMS backup format. I've had some success using the vmsbackup utility from comp.sources.unix but it is rather old (based on VMS 4.?) and won't always extract the files. When it fails we have to go through our friendly neighborhood vms system, but they are so short on disk space that it is a real challenge to get our huge data files off tape there. Is there a newer version of vmsbackup floating around somewhere? Seems like DEC should supply such a utility for Ultrix to help VMS and Ultrix systems get along. Failing that, is there a description of the current VMS backup format somewhere that I might use to patch up vmsbackup? I don't have VMS manuals on hand but I can borrow them if I know what to ask for.

Failing that, is there a description of the current VMS backup >format somewhere that I might use to patch up vmsbackup? Can I reiterate this enquiry, as well as the admonition to DEC. I've never been able to find any format information in the VMS manuals, and we don't have source at this site. I just grabbed a copy of vmsbackup, for a similar application. On a DECstation 3100/Ultrix 4.0/RISC, it generates heaps of alignment errors: code in process_file assumes that the struct bsa elements in the buffer passed to it are aligned. The fix seems easy enough - just perform a byte-by-byte copy into an aligned temporary. I wonder if this could be associated in any way with Don's problems? Can anyone out there offer definitive advice? Russ Evans British Geological Survey
