- 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.
-
-
- Version 2.2A - April 1992
- -------------------------
- Added new file compression routines which speed up backup with compression
- by 30%. Backup time estimates have been adjusted to more accurately
- reflect averages for common file type distributions.
-
- Removed VALIDATE command. Added TEST command to RESTORE menu which goes
- through a restoration without actually restoring files to the hard disk to
- verify that the backup disk set is in good working order. Note that each
- file from the backup set is restored to the Point & Shoot Backup/Restore
- directory with the name PASBRTST.$$1 and then deleted.
-
- Backup is not allowed to run from floppy disks. Previous versions
- should not have been run from floppies because of conflicts in the backup
- program when low-level disk parameters are modified during backups but
- the program did not restrict operation to hard disks. Restoration may
- still be operated from floppy disk.
-
- Removed /C command line parameter for special compatibility mode. Some
- users get errors trying to backup. The /C parameter made a small change
- to the program to attempt to fix "Bad Disk" errors. This command line
- option has now been moved to the Backup Configuration screen and is called
- "USE COMPATIBLE FIXUP?"
-
- "INCLUDE TRAILS?" on Backup Configuration screen now just reads "TRAILS?"
-
- Added warning to not use prior backup disks if MODIFIED FILES ONLY option
- is selected. MODIFIED FILES ONLY is used to add new disks to a prior
- backup set. These new disks will only contain files modified since the
- last backup. You must keep the original full backup set and any backup
- sets created with MODIFIED FILES ONLY to be able to restore everything at
- a later date.
-
- Included new installation program which eases installation and updates
- backup and restore configurations from older versions.
