- Back and UnBack are a pair of raw utility programs that I wrote
- to make using Matt Dillon's BackUp/Restore program safer and faster to use.
- These programs essentially replace the AmigaDos Copy command when saving
- (and restoring) the large backup files to floppy disk.
-
- "Back" is used to copy a single large (up to about 860K) file to floppy
- disk in a special non-dos format. This is much the same thing the
- old utility "DosKwik" used to do with two exceptions DosKwik was more
- versatile (it could copy directories and files larger than a floppy)
- but DosKwik did not verify the copy. Back does verify each track after it
- has written it to disk (I tested this with several known bad disks) to
- make certain that when it come time to restore your hard disk the floppy
- disks containing your backup can actually be read.
-
- "UnBack" is used to restore previously backed up disks.
-
- Source code is included in the hope that someone who is interested will
- extend these utilities to include recursive copying of directories and
- handling of files larger than one floppy (I may do this myself some day).
