- MULTIBAK V2.3 Gilbert Shapiro REGISTRATION $20.00
- UTILITIES BACKUP SHAPIRO FILE
-
- New Release
-
- Many microcomputer programs that modify files, such as word
- processors, data base managers, and spreadsheets, provide
- for a single generation of backup, usually renaming the old
- version of "filename.ext" to "filename.bak" before writing a
- new "filename.ext" to disk. When a new revision is again
- saved, the backup file saved earlier is wiped out. This is
- not always satisfactory. Who hasn't changed his mind later
- and wanted to return the file to its state several
- generations earlier? Sometimes, we discover a major error
- several revisions later, and the loss of earlier versions
- seriously sets back our work.
-
- For these reasons, some mainframe operating systems (such as
- VAX/VMS) provide the option of saving multiple generations
- of backup. Not only the previous version of a file, but as
- many generations as the user wishes (or as many as can fit
- in his disk space) can be preserved. MULTIBAK is a set of
- programs intended to provide the same facilities for IBM
- compatible PC systems.
-
- Any computer work that creates multiple changes in files can
- be made less frustrating and safer from disaster by using
- this collection of programs. When editing a document,
- writing a program, or developing a spreadsheet, for example,
- one might create a backup almost at the stroke of a key
- whenever significant changes are made, accumulating versions
- until a final product is completed and verified. Of course
- this can also be done by means of DOS commands, without the
- use of a special program. One would examine the directory
- to see what file name hasn't yet been used, then use the DOS
- RENAME or COPY command to create the backup required, and
- then save the current version. Ultimately, we also have to
- erase the backups, and we are not always in a position to
- use wildcards safely. We don't usually do all of this,
- because it is a lot of trouble and distracts us from our
- work. MULTIBAK does it for us, conveniently, with little
- distraction. Like a more comfortable seatbelt, it adds to
- safety because it is more likely to be used.
-
- The freely distributed version provides two versions of
- MULTIBAK: one which copies the file and one which renames
- it; a thorough documentation file; and PURGE, a program for
- conveniently and safely erasing backup files. Registered
- users receive, in addition, two memory resident versions and
- two additional utilities: REVERT, which quickly and simply
- returns to an earlier version of the file while preserving
- the current version, and RENUMBER, a facility to change a
- broken series of backup names to an unbroken sequence.
-
- Hardware Requirements : IBM compatible computer.
-
- Other Requirements : DOS 2.x or higher.
