OffLoad-Archive System
Problem Description:
It is a well established fact that files residing on hard
disk drives on any type of computer will follow Parkinson's
Law (The number of files will always expand to fill the
disk on which they are held). This problem is further
compounded by a quirk of human nature that is loath to throw
away any file for fear that it will be needed at some
indeterminate point in the future.
The result of these two forces of nature is ever increasing
requirements for storage space to accommodate more-and-more
files that are used less-and-less frequently. It makes no
difference how large the hard disk is on a PC this phenomena
WILL OCCUR.
Most users attempt to solve this problem with various
patchwork schemes. Many use general purpose archives to
compress files and hence use less space. This only delays
the problem. Soon there are archive files spread around all
over the hard disk and there is still no space left.
The next step generally involves copying these archive files
off to a floppy disk to free up the hard disk space. This
raises a new problem. How do you keep track of these files
once you have moved them off the hard disk to floppies? How
do you find the file you need when it is time to move it
back to the hard disk? Many of us tried to solve this
problem through the use of disk catalogers. FBN Software
markets such a program. However these programs only solved
part of the problem and added additional steps to the
process.
This is the way things generally work today:
1. Compress files on hard disk with a general purpose
archive.
2. Copy files from hard disk to floppies with a file
manager or DOS COPY command.
3. Place a unique volume label on floppy disk to be
able to identify the disk.
4. Catalog the floppy disk with a disk cataloger.
5. Print labels for your floppies so you can tell
which ones they are and store the floppy.
Now to bring a file back:
1. Bring up your disk cataloger and locate the floppy
disk that contains the file you're looking for,
and get the floppy from it's storage box.
2. Exit the cataloger, bring up your file manager and
copy the file to your hard disk or use DOS COPY.
3. Use your general purpose archive to decompress and
extract the file.
Problem Solution:
Now lets take a look at what OffLoad does to this process:
1. Use OffLoad's point and shoot interface to
identify files to be archived. OffLoad then
compresses these files, copies them to a floppy
disk, records their location in a catalog.
2. Place a label on the disk that contains the
archive name an disk number (We provide a supply
of these labels to registered users.) and store.
To bring a file back:
1. Use OffLoad to search for and identify the
required file. OffLoad will tell you which floppy
to place in floppy drive. OffLoad will restore,
and decompress the file into it's original
directory or any directory you choose.
OffLoad greatly reduces the amount of work you need to
perform. To archive a file it reduces the number of steps
from 5 to 2. To bring a file back it reduces the number of
steps from 3 to 1. OffLoad will give you better control over
files that you archive than you have over files on your hard
disk.
OffLoad was designed to solve these problems. Think of
OffLoad as a combination of three products in one. OffLoad
has the compression capabilities of general purpose archives
such as ZIP, PAK, ARC, LZH. It has the file movement
capability of a file manager. Finally, it has the catalog
and search facilities of a disk cataloger.
OffLoad will allow the PC user to identify files of any type
to be placed in archive. The files are compressed, copied to
the archive on a floppy disk , and deleted from the hard
disk (User Option). A catalog is used to manage and keep
track of all files placed in the archive. When a file is
needed from the archive the user simply selects the file
name from the catalog and OffLoad will request the disk
containing the file be placed in the floppy drive. OffLoad
then decompress, and copies the file to the file's original
directory or a user selected directory on the hard disk.
Program Description:
OffLoad is designed to perform data archiving and retrieval
for PCs in a manner similar to equivalent functions in the
main frame world.
OffLoad will allow the user of an IBM PC or compatible to
archive files from the hard disk to a floppy for permanent
storage. A catalog of archived files is maintained on the
users hard disk to facilitate management and retrieval.
All files placed in the archive are compressed and written
to the floppy in a such away so that a greater amount of
data can be stored on each disk.
Some OffLoad Version 1.0 Features:
1. Move files to archive. There are three methods:
1. Manual-Point and shoot.
2. Auto-Move files by extension that are over (X)
days old.
3. Scheduled-OffLoad provides a command line
scheduling utility to schedule files for archiving
the next time OffLoad is run or some date in the
future.
2. User assigned Keywords on each file (optional).
3. Automatic Save & Backup of Catalog after files are
placed in the archive.
4. Restore of catalog to hard disk from archive.
5. Restore files from archive.(To Original or New
Directory)
6. Generate reports on files in archive (Printed &
Display).
7. Compress all files in Archive except ARC, PAK, ZIP, LZH
general purpose archive files.
8. Read and store in catalog directories of ARC, PAK, ZIP,
LZH general purpose archive files.
9. Catalog search functions include:
1. File Name (Wild Cards Supported)
2. Keyword
3. Date of Archive (Bracketed Search)
10. OffLoad uses a 16 bit CRC to verify file integrity on
restore.
11. Menu driven interface.
12. Mouse Support.
13. Full context sensitive help screens.
