I think you are confusing "backup" with "archive." In my lexicon, a
"backup" is a copy of my current system (or part of it) for use in case
of system failure. An "archive" is a record of some past system content
that I wished to save for possible later use. I would never consider
using a backup utility to produce an archive record, and I wonder what
ever gave you the idea to try, especially since BACKUP does not compress
records. The only virtue of BACKUP/RESTORE is that they will read all
the files to be backed up (including hidden/system files) and when
restored, all the original attributes (except the archive bit) will be
restored. Unlike my backup files, my "archive" records (some of which
date from 1983) are kept either in "clear text" or (at most) as ZIP or
ARC files with a copy of the corresponding UNZIP (or UNARC) file on the
same diskette. It doesn't matter what directory they came from.
Since the backups are records of current contents of my hard drive,
there is no problem in knowing which directory the original was stored
on, since it still exists. The "oldest" backup ZIP diskette I have was
written about three months ago: it was made the last time I wrote to the
partition that contains my compilers (I added a fixpak to the PL/I
compiler). Thus, my backup diskettes represent current hard-drive
partitions, more-or-less as they currently exist. They are replaced by
a new backup of the same partition whenever it seems to be a good idea
to do so. (Copies of data files are updated as a portion of every
session in which those files are modified. I suppose they can be
considered to be a form of backup in which I use XCOPY, rather than
BACKUP, to a diskette used only for that set of files,)
