[comp.sys.mac] Summary of HD backup program responses.

tim@j.cc.purdue.edu (Timothy Lange) (03/05/87)

The following is my summary of responses to "What do you use to backup
your Macintosh Hard disk?"  I have received six replies after waiting
three weeks for replies to trickle in.  Not much of a return I am afraid.

Three people use HFS Backup from Personal Computer Peripherals Corp.  $40
One person uses SuperBackup from SuperMAC.  $??
One person uses HD Backup from FWB software.  $35
One person uses DiskFit from SuperMac Software.  $70-80

I use HFS Backup from Personal Computer Peripherals Corporation (the
makers of the MacBottom hard disk).  It does full and incremental
backups.  You must use the program to restore files--you can't just
drag them back from the backup disks.  It will backup files larger than
a single diskette, and can use either 400 or 800K disks for backup.  It
(optionally) checks the disks before and after backing things up on to
them.  You can specify specific files to back up (or specific files NOT
to back up).

It costs around $40, and is available mail-order or direct from PCPC,
whose memorable phone number is 1-800-MAC-BUTT.

I use SuperBackup by SuperMAC, a program that was bundled with my
DataFrame hard disk. It does volume, incremental and selected files
backup and restore in a straightforward manner. The only thing I miss
is the ability to backup a single folder without having to select all
the files of the folder (the select function applies only to files,
with a shortcut for selecting all files in a given directory that are
not in a sub-folder (if you understand...)).

SuperMac claims they'll be releasing a much enhanced version, which I
have not seen.

Whatever you do, you do not want a program that does an image backup.
It makes incremetnal backup impossible, and does not allow you to
restore selected files (as opposed to volume backup).

I use HD Backup from FWB software.  It packs files into a special
format and backs up one chunk per floppy.  This means there is less I/O
and the program runs faster.  They support complete and incremental
backups and backing up and restoring selected files.  This program does
everything I want.  The backup format is readable only by the backup
program.  I have had occasion to restore selected files and it works
quite well.  You tell it what you want and it say "insert disk 12" or
whatever and it gets restored.  My original copy had a bug in it, by I
wrote them and they sent me a new version which has worked ever since.
I don't recall what version I have now, but I can tell you if you need
to know.  In other words, this program (~$35) is just what I wanted it
to be and is much faster than copying folders by hand.

I use HFS Backup from Personal Computer Peripherals Corp. on a Photon
20 SCSI hard drive; I assume that it would work on any SCSI drive that
was formatted for HFS.  It works very well and allows total and
incremental backups.  There's a new version (2.0) out, but I haven't
seen it yet.  You should be able to get it for around $40 from discount
places.

There is a new program for backing up the contents of hard disks onto
floppies, joining the likes of HFS Backup, Flashback, HD Backup and
others of their ilk.  The program is published by SuperMac Software, a
spinoff from the company that makes DataFrame hard disks and memory
upgrade products; it was developed by Dantz Software Development of
Berkeley, CA.  I looked at the product at the SuperMac booth at the
January MacWorld Expo in San Francisco, and received a photocopy of the
first eight pages of the manual from Dantz in response to my inquiry.

The product differs from many other hard disk backup products in at
least two ways:

1) It stores files on the backup disk in Finder-readable format, rather
than in some compressed or encrypted format (with the exception of
large files split over more than one disk, which are
Finder-copyable/deletable files which must be joined before they are
usable as applications or data files.  This greatly enhances the
integrity and usability of the backup copies, particularly if the
"backup directory" common to many other backup programs is lost or
damaged (and usually, this directory is placed on only one disk,
although it can--and should--be copied to others), or if the backup
program itself is in some way unavailable.  It's also more convenient
to Finder-copy a backup of a file back onto the hard disk, rather than
having to run the backup program each time you want to just restore one
file.

2) It does intelligent incremental backups.  That is, if one adds or
deletes files from the hard disk, the backup program will also add or
delete these files from the backup set.  This feature means that it
will always take, for example, 30 DS floppies to backup a full 20MB
hard disk, rather than taking 30 floppies for the first backup plus an
additional 1-5 floppies each week/month/backup period.  This not only
eats up additional floppy disks unnecessarily, but also makes the
process of restoring a hard disk much longer, as more disks are
involved in the restore.

The product is called DiskFit.  It will sell for something like $70-$80
list (probably 50-75% of that price at discount), and should be out
right about now (I haven't yet called any dealers to see if it's in
stock, but I'll probably be doing so very soon).

I don't know if this program is fast, reliable, or any of the other
crucially important things one wishes a hard disk backup program to
be.  It looked pretty good when demoed, but that don't mean nothin'.
It is definitely worth checking out, however.  I've played with a
predecessor program from Danz, called MegaCopy, and used it to copy
(via backup and restore) ~16MB of files from a MacPlus w/HD20SC to a
512K Mac w/external 800K disk and HD20.  It was no picnic, but it was
reasonably fast and worked reliably.

Disclaimer:  I have no connection with either SuperMac Software or Danz
Software Development, or any of their employees, other than as an
interested prospective purchaser of their products.

I currently use HFS Backup.  It does full and incremental backups.  It
also can do selective backups.  You can even tell it not to back up
certain files.  It works fine, but I'm considering a switch to tape
backup because I'm tired of pushing 20 diskettes into the drive every
time I do a full backup.  Also, each incremental uses at least one
diskette.
