Does anyone have software which will backup the DOS partition on the
hard disk from unix or xenix? Please don't suggest using dd, if you've
tried you know why that's not the solution.
I need a backup which will move DOS data structures between machines,
vendors, and partition sizes. Ability to backup only part of a disk
would be useful but not required.

That's not a complete solution of course, but it is useful and might be a good starting point. I like to move files around by using zoo under their native OS then copying to msdos formatted floppies. As a worst-case scenario, you can always extract the files on a PC and download them to a new machine with a communication program. Too bad zoo doesn't handle multiple disks or writing to stdout...

If you have VPIX you could run one of the DOS cpio's in a pipe. Even PC-Backup on a file (even UNIX char special?) should work. |> -- |> bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) |> sysop *IX BBS and Public Access UNIX |> moderator of comp.binaries.ibm.pc and 80386 mailing list |> "Stupidity, like virtue, is its own reward" -me -- ---- Thomas M.

Well, this is what /etc/dfspace says I have mounted: / : Disk space: 7.16 MB of 20.48 MB available (34.98%). /usr : Disk space: 8.34 MB of 52.67 MB available (15.85%). /usr/u : Disk space: 6.87 MB of 14.62 MB available (47.01%). /usr/src : Disk space: 7.45 MB of 31.19 MB available (23.89%). /usr/spool/news: Disk space: 9.70 MB of 32.83 MB available (29.54%). /dos : Disk space: 3.45 MB of 12.47 MB available (27.67%). Total Disk Space: 42.99 MB of 164.29 MB available (26.17%). (not much, but enough for me :-) Now, every saturday morning I run sysadm backup to backup the entire system, dos and all, with incremental backups, relative to the last full backup not just any backup, nightly. You do have to make sure that NDOSINODES is set high enough, or Unix will not be able to read in all of the dos "inodes" into core. (There are no real dos "inodes" but unix, (my unix? ISC2.2) maintains an incore list of inodes for all dos files.) The first few times that I was doing a backup of /dos I would hit the same problem. So I increased NDOSINODES and rebooted. Works like a charm now...
