Ami-Back is a state-of-the-art hard disk drive backup utility for the
Commodore Amiga line of personal computers. Ami-Back makes the job of
backing up hard drive data quick and easy to do! Included with Ami-Back is
Ami-Sched, a scheduling program that directs Ami-Back to perform backups
without user interaction.
This DEMO is of the version of Ami-Back written for users of AmigaDOS
1.3. When you purchase Ami-Back, you will get both the 1.3 and 2.0
versions on the same disk. That way, if you should move up to AmigaDOS
2.0, you won't have to go through any upgrade hassles!
USING DEMO
1) Copy program to your hard drive; preferably to the sys:tools
directory.
2) Execute the program either from SHELL or from WorkBench using the
icon.
3) Set up the backup configuration (see menus). Save your
configuration. You should set up the Program Configuration also.
The log file, index file(s), and File Exclusion Filter all default to
the sys:s directory.
4) Most of program functions should be self explanatory. There are no
docs included with the DEMO version. A detailed manual is included
when you purchase Ami-Back.
5) You will be able to perform backups to floppies, removable hard
drives, and/or hard drive partitions, and SCSI Tape drives.
NOTE: Applied Engineering's driver for the High Density Floppy drive
currently does not work under Kickstart version 36.314. AE is
working to correct this problem.
General Information:
1) Backs up any Amiga hard drive to any AmigaDOS compatible device such
as:
Floppies (conventional or high density)
Removable media hard drive(s)
Fixed media hard drive
SCSI Tape drive
AmigaDOS File or device
2) System Requirements:
- Any Amiga Computer A500/A2000/A2500/A3000
- Requires AmigaDOS 1.3 (for this version)
3) Installation:
- Installation program is provided to install the Ami-Back/Ami-Sched
programs on the users hard drive, and update the Ami-Back.config file
of their location.
4) Technical Support:
- Technical support will be provided to REGISTERED OWNERS of Ami-Back
via Phone, BBS, BIX, and GEnie. Phone numbers and accounts are listed
in the owner's manual and in the "about" screen of the program.
Features:
Scheduler:
1) Includes versatile scheduler similar in concept to the UNIX cron
program, but with a sophisticated, easy-to-use graphical interface.
2) Allows unattended backups based on user defined intervals. (Types:
Complete, Incr by Date, Incr by Archive Bit)
3) Especially useful for users with tape drives or removable media.
4) Configured within the main backup program.
5) Runs in background. Can be initiated from Shell or Workbench icon.
6) "Multi-tasking friendly." Uses virtually no system resources.
Backups:
1) User-interface of the 1.3 version designed to operate like the
Workbench 2.0 interface.
2) Configuration files:
a) For creating and storing user defined options for scheduling,
backups and restorations. Also used to define locations of support
files.
b) Superb flexibility with total user control.
3) Size of backups are virtually unlimited.
4) Backup Types:
a) Complete (entire device and/or directories)
b) Incremental (by date, archive bit)
c) Selective (hierarchical inclusion or exclusion by file or directory)
5) File exclusion filter:
Allows exclusion of files during all types of backups using AmigaDOS
wildcard metacharacters. Up to 100 exclusion conditions are allowed
simultaneously.
6) Allows setting of archive bit during backup.
7) True verify mode during backups. Re-reads data from backup media and
compares it with source data to ensure integrity of backup.
Restores:
1) Restore Types:
a) Complete (entire device and/or directories)
b) Selective (hierarchical inclusion or exclusion by file or directory)
2) Allows user to restore to previous directory hierarchy from the backup
or to a single user specified device/directory.
3) Allows user to control protection bits or use original bits (by
default).
4) Allows user to specify current system date or retain original file
dates (by default) from backup.
5) Duplicate file detection:
a) Write-Over (overwrites existing files)
b) Skip-Over (restores only files not found on target device)
c) Re-Name (allows user to rename the files restored from backup which
are found on the target device)
Special Features:
1) Compare:
Located on the restore configuration screen, this feature allows the
user compare the data stored in the last backup and the data currently
on the target device. Compare maybe used in the event of suspected or
real hard drive corruption to check for lost or damaged files.
2) Log file:
Logs all tasks performed by scheduler and errors detected during
background backup operations.
3) Index File:
Indices are stored for each backup. Index naming scheme includes:
device backed up, type of backup, date of backup, and sequence number
if needed.
4) Back-Tracking:
During backup, if a defective destination floppy is detected, the
program will allow the user to replace the defective media and resume
the backup without interruption.

SCSI
These results represent only one of the many configurations Ami-Back
has been tested with. SCSI controllers tested include: Commodore
A2091, GVP Series I and II, and Microbotics Hardframe. Ami-Back will
also work with the Commodore A2090A for backups to floppies and
hard drives. The A2090A does not work well or at all with tape drives
tested.
