The above is true and the suggested solution does work.  But your old
backups are not worthless as long as you RESTORE with the proper version.
The best solution for all this is to make sure that all your PCs are upgraded
to the same version of DOS, and when you do upgrades, do ALL the machines.
Also, if you ever ship a set of BACKUPed disks to someone, send along a DOS
bootable system disk with copies of BACKUP/RESTORE from the system you got
the BACKUPs from.  This way they can RESTORE regardless of what they run.
Just make sure *they* are aware of the potential incompatabilities between
DOS version.
