POINT & SHOOT BACKUP/RESTORE REVISION HISTORY Version 1.0 - June 1988 ----------------------- Original version of the program released Version 2.0 - May 1990 ---------------------- Revised program SETUP to match drive specification of version 2.0 of the Point & Shoot Hard Disk Manager. Program now allows use of external floppy disk drives with letters higher than B and can be executed from any drive or directory. Improved disk formatting routines Increased directory tree capacity to 255 entries Added file compression option (approx. 50% average compression ratio) Enhanced backup speed with direct format/write loop. Backup approaches 1 megabyte per minute on 1.2MB or 1.44MB disks. Added file selection list on restoration for easy single file restorations. Added ability to make subdirectories during restoration if files are restored to other than the original path to allow user to have complete control over the structure of the hard disk to which files are restored. Enhanced error detection/recovery Added single file compression/decompression routines to assist in reconstruction of files outside of the restore process. Added parameter option to immediately move into and execute any one of the 10 backup configurations: PASBR 1..10 Revised and enhanced program documentation Version 2.0A - September 1990 ----------------------------- Added an error number message for backup errors that do not have descriptions. This error number is useful when calling for support if an unknown error occurs during the backup process. Version 2.0B - September 1990 ----------------------------- Made a minor change to backup routines to correct a bug with some computers and 3.5" drives being unable to write system area to disk. Added /C command line parameter to force temporary files to be written to current directory. Version 2.0C - October 1990 --------------------------- Fixed a bug in the backup routines that caused unreliable backups to be made under certain circumstances. Problem did not show up until restoration was attempted. Version 2.0D - January 1991 --------------------------- Fixed a bug in use of external drives for backup. Previously gave an invalid drive request error for drives higher than D. Version 2.1A - February 1991 ---------------------------- Several bugs were fixed in version 2.1A. A variety of errors were reported by users when backing up or restoring disks. Among these errors were bad clusters appearing on the hard disk after backup and "file not found" errors during restoration. These problems have been corrected. VALIDATE command was added to allow the user to check a set of backup disks to determine if they would restore correctly. If any problems were found, they are corrected. USERS OF VERSION 2.0 should run VALIDATE on all sets of backups disks made with version 2.0.
