- BACK2FT2.DOC
- --------------
-
- BACK2FT2.CMD is the modified version of Ralf Hauser's original
- BACK2FAT.CMD. With his "best wishes", I have made some minor
- changes to the original program which will now allow for using
- the program with PKZIP and ARJ as well as with ZOO.
-
- Changes in Version 1.02:
- ------------------------
-
- - added the ability to backup with PKZIP and ARJ
- - added more flexibility via command line switches. most
- notably;
- - the ability to uniquely name the "filename" portion
- of the output file set.
- - designate which utility program to use
- - convert all command line arguements to upper case
- for easier manipulation
- - inserted additional code necessary to handle mul-
- tiple compression utilities
-
- Notes:
- ------
-
- If you are a registered user of the ARJ compression utility, the
- "tmpfile" filelist approach used by Ralf will work although the code
- in the b2f_backup procedure will require further, slight modification.
-
- Also, using the ARJ utility, the '-b1' switch can be added to make
- backups to an already existing backup file with the same output file-
- name.
-
- I have not made any allowance in this version for return codes other
- than what was originally specified. This should be done in order to
- act properly when ARJ or PKUNZIP fail to compress properly. I have,
- however, increased the return code value to any code > than 2 which
- seems to correct the ZOO problem specified by Ralf in his documenta-
- tion.
-
- Caveats:
- --------
-
- I have not tested the quality of the compressed files by doing a full
- restore. I have performed restores on test sub directories and all
- seems to work correctly. The program does accomplish the desired
- end and has given me the solution to the "HPFS to FAT" backup problem
- using a DOS-based tape drive.
-
- Operation:
- ----------
-
- I have created a 75mg FAT drive which I use as the receptacle for my
- backups and which is totally dedicated to this end (what a waste!).
- Be as it may, after I have run this utility and Dave Terry's WPSBackup
- program for preserving the desktop, I have a directory structure which
- looks like the following:
-
- SubDirectories Usage
- G:\ TEMP Used to keep copies of BU utilities
- EAJD Backed up files/ea's from Drive D:
- EAJF Backed up files/ea's from Drive F:
- WPS Backed up desktop
-
- The process I have used is to first backup the WPS Desktop.
- Run the BACK2FAT program to preserve files on HPFS drives D: and F:
- To accomplish this, BACK2FAT must be run twice. I have set up a pro-
- cess to accomplish the first two procedures on a timed basis at night.
- The last step is to reboot DOS 5.0 and run the tape backup program
- which performs a full backup on Drive G:. This also may be done auto-
- matically by using the "timed approach" from within DesqView.
-
- ----------------------------------------------------------------------
- I hope that you find the two versions of BACK2FAT usefull. Should you
- elect to make further modifications, please include the new "version"
- with the original package along with your documentation of changes.
-
- Please send copies of changes to Ralf at the address stated in his
- documentation and to me. Good luck!
