MRBackup Feature Overview
Last Update: 01/16/93
Version: 1.13
Orders: See "Ordering Information"
MRBackup Professional is a feature-laden hard disk backup program
for the Amiga tm family of computers, providing the following
features:
- Employs the Amiga's Intuition graphical user interface.
- Context-sensitive hypertext help via AmigaGuide tm
- Employs AmigaDOS speech capability as a very effective
attention-getting device (disk changes, error messages, etc.)
- Operates under AmigaDOS versions 1.3, 2.04 and beyond.
- Backups may be done to floppy, streaming SCSI tape (including
DAT) or sequential file/device.
- Highly configurable - different "project" settings can be saved
to individual files.
- Provides flexible data compression/decompression with
user-tunable compression factor.
- Supports incremental backups via modification date and/or
archive bit testing/setting.
- Filename "filters" are provided to enhance backup and restore
file selection.
- Rich ARexx command set to provide full or partial control of
backups/restores and parameter settings. Scripts can be invoked
externally (rx scriptname) or via user-customizable menu entries.
- Built-in file management utilities.
- SCSI tape handler included - may be used with other programs.
Multiple savesets may be stored on a single tape. Savesets may
span multiple tapes.
- Many more features.
MRBackup Pro sports 3 backup modes - AmigaDOS, "Fast Disk" and SCSI
Tape. The "Fast Disk" method organizes directories, files and data as
a sequential stream with embedded structure and error recovery
information and enables much higher throughput when using floppy disks
as the backup medium. The "Fast Disk" format is also used when
writing streaming SCSI tape. Another very special feature of the
"Fast Disk" format is that it can be directed to/from a file (local or
networked) or any sequential device. If you are fortunate enough to
have your Amiga hooked up to a network with a high-capacity file
server, you can backup over the network. To the remote filesystem,
the backup set just appears to be a stream of bytes. The
Amiga-specific file attributes are safely encapsulated in the "Fast
Disk" envelope and therefore do not need to be translated into
approximations on the remote filesystem (potentially losing or
corrupting useful information).
When running under AmigaDOS 1.3, MRBackup Professional employs the ARP
(Amiga Resource Project) library for its file requester and date
manipulation support. When running under AmigaDOS 2.04 and beyond,
the Amiga's standard ASL file requester is used. Some users are
confused by this, thinking that a full installation of ARP (and
replacement of original Amiga programs) is required. This is not the
case. It is only necessary to copy the library to your LIBS:
directory (done by MRBackup's installation script) and this will IN NO
WAY interfere with your other software.
MRBackup Professional comes bundled with its own tape handler. Most
of the major vendors' tape drives are currently supported (Archive,
Sony (DAT), Wangtek, Tandberg, etc.) and I am committed to adding
support for any other "standard" drive which can be configured for
Amiga use. While SCSI defines, in a general sense, the methods to be
used when talking to a tape drive, there is a surprising amount of
variability in the capabilities available from the various tape drives
and the methods employed to tap those capabilities. The included
mrtape-handler builds upon a known common denominator and then
fine-tunes itself by interrogating the drive for additional
information.
MRBackup Pro supports software data compression (LZW method) which
will allow more data to be packed onto the backup media. Compression
results will vary with the content of the data, but run typically from
35% to 65%. The user can control the degree of compression by
selecting the number of bits in the compression codes (12 - 16).
Higher code sizes yield more efficient compression but require more
memory and time to achieve it.
The user interface is fully "Intuitionized", allowing the user to
point-and-click when setting just about any option. MRBackup's many
features are represented by a series of windows and their "gadgets".
Almost all operating parameters may be controlled simply by pointing
and clicking with the mouse. The user may load/save custom parameter
sets via menu selection or ARexx control. When a backup or restore is
initiated, a Status window which reports the progress of the backup or
restore and even provides "buttons" to pause/resume or stop the action
in progress.
MRBackup can be started either from the CLI or the WorkBench. The CLI
interface supports several optional command-line parameters. The
MRBackup project icon supports several equivalent ToolType entries for
establishing MRBackup's initial operating environment.
If you wish, MRBackup Pro will talk to you, using the Amiga's built-in
speech capability. This may seem silly until you realize that you can
leave the room and MRBackup will call you when the next floppy disk is
required for a backup or restore or when an error condition requires
your intervention.
A special Utilities window can be activated via menu selection. This
allows you to perform a number of useful functions on individual files
or groups of files (copy, delete, rename (move), compress, decompress,
set date, etc.).
Incremental backups may be performed, using the file modification date
or the file "archive bit" (or both) as the criteria for file
selection. MRBackup Pro can be directed to set each backed-up file's
archive bit, as well. Filter files (text files containing filename
patterns - wildcards are supported) can be employed to further refine
the set of files selected for backup or to inhibit
compression/decompression on certain files.
When a backup is started, MRBackup builds a list of all files eligible
for backup. This list is presented to you via a special file
selection requester which has many features for navigating and
"pruning" the list. MRBackup Pro doesn't just copy files to the
backup media in the order that they were scanned. All
files/directories are output in sorted order or in "native" order,
depending upon the user's preference. All file attributes (file
creation/modification date, comment, protection word, etc.) are
preserved by the backup/restore process.
Upon completion of a backup, a "catalog" file describing the backup
set is created and stored at a location of your choosing. This can be
on a separate floppy disk or in a special location on your hard disk.
What if you lose the catalog file? No problem! The Rebuild Catalog
command will let you recreate it.
A formatted listing of your backup set is generated for you, if you
wish. Also, MRBackup will create a log file of the backup or restore
process, recording any errors or noteworthy events that occur along
the way.
Upon starting a restore operation, MRBackup Pro reads the previously
created catalog and presents the file selection requester to you (or
you can ignore the catalog if you're doing a full restore). You may
then easily select all, some or only one file to be recovered from the
backup set. If you happen to select the last file on the last floppy,
you won't have to "wade through" scores of backup disks. MRBackup Pro
will simply skip the backup disks on which no files have been
selected. MRBackup Pro will not overwrite files which are newer than
their backed-up versions unless you enable the "Force Copy" option.
MRBackup Pro also sports an ARexx port which allows you to control
just about every aspect of its operation from an ARexx script. Using
a public domain program such as "dcron" or "AmiCron" in conjunction
with the appropriate script, you can schedule automatic backups at
intervals appropriate for you.
This should give you a useful overview of MRBackup Professional's
capabilities, though there are many, many more features available and
new features are being regularly added. If you have any specific
questions, please don't hesitate to ask.
