Here at AT&T GSL, we do software development on an assortment of 6300s, 6300+s, and AT clones. We each have a machine at work, and another at home. The problem is when we go home at night, we need to take along updates of files that changed during the day. These files are spread across many directories, and often may exceed 10 MB. The problem is how to do this quickly and easily. Our first fated attempt was to get a Plus Development 20M HardCard to share. This is fast, especially with the XCOPY command in IBM DOS 3.2. But if we format the HardCard for IBM DOS 3.1 or 3.2 (the only thing that will run in the ATs) then we can't read the card in the AT&T machines. And vice-versa. We haven't been able to find a version of DOS that will work in all the machines *and* also be able to read and write the HardCard. Second attempt was similar to the first - make cables for each machine to bring out it's HD controller's cables for a second bare hard disk, and move the harddisk from machine to machine. Also fast. But same results. Apparently IBM DOSs write on the harddisk slightly differently than AT&T DOSs. Getting more desparate, there are two alternatives: floppies (oh gawd no) and a tape backup system for each machine. So for the questions: Floppies: I've seen software (e.g. Fastback) that makes backing up tolerable on floppies. Which ones are likely to work on all the different machines? and also work comfortably across multiple directories copying only those which have been modified since a certain time? Tape backup: What units have you used? Does their support software permit backing up only certain files across multiple directories automatically (no cds to each directory) and how long does it take to do, say, 10M of those files? I'll post a summary in a couple weeks. Thanks in advance.. Bob Rindfuss AT&T Graphics Software Labs ...ihnp4!inuxh!rdr (317) 352-6147
