FASTBACK has a number of nice features:
- It is no longer copy protected.
- It is fast.  I average about a megabyte a minute on 360KB floppies,
  including disk change time.
- You can do incremental backups.  These can be appended to your full
  backup, starting on the last (partially filled) disk.
- FASTBACK maintains an on-line catalog, which you can browse to find
  all backups (versions) of a file, then restore the one you want.
  Browsing and searching are pretty fast.
- You can use a control file to specify multiple file specs to be
  backed up, and other options.

You can simulate multiple catalogs (backup sets) by renaming the catalog
file.  I use two catalogs.  One, for large files that change frequently,
I always back up to the same three floppies.  The other is an
incremental backup onto the tail of my last full backup.  The idea is
not to let multiple copies of system log, databases, editor swap file,
etc. from expanding my incremental backup too fast.  My daily backup
takes 2 to 3 minutes (faster than most tapes!).

The floppy format is not readable via DOS commands.

The command line is not well designed.  Parameters are purely
positional, and values are not checked, so it's easy to make a mistake.
For example, FASTBACK will take "c:\etc\*.*" as a valid answer to a
"yes/no" option.  You may not want to abort a backup when you see it's
going wrong (see next paragraph).  I only run FASTBACK from carefully
constructed batch files.

FASTBACK has one major bug: if you abort an incremental backup, even
before it writes anything to the disk set, the backup catalog is
deleted.  This means you cannot do further incremental backups to that
backup set.  You can still restore files from the set, but the RESTORE
utility must now search through the floppies one by one to find a file.

I've been reading the responses to this base note because I'm also
interested in finding a good backup utility.  However, most of the 
negative responses have been little use in judging FASTBACK because
the authors of those responses have not indicated what version they
were using.  I think the current version is around 5.1.

When trying to decide which software package to buy, the bugs of past
versions are of little interest as long as they've been fixed (there 
will be some interest if one is trying to judge the track record).

I am not saying that those who are using (have used) previous versions
should not respond.  Their input would be valuable to those trying to 
decide whether to upgrade or not.  What I am saying is that the input
is worthless unless the version number is included.

This applies to all evaluations of software.
