[comp.sys.mac] Fastback II offer: is it a good dea

dantz@cdp.UUCP (06/28/89)

I'd like to propose an alternative to the Fastback II
offer.  DiskFit from SuperMac Technologies offers fast,
reliable backup at a lower price.  DiskFit is available
through various mail order houses for around 60 dollars.  



DiskFit is a very reliable program which backs up your
files in Finder format to floppies and other media that
mounts on the desktop.  This means that when you want
a particular file from your backup set, you can insert
the disk and drag it back to your hard disk.



DiskFit does an image backup.  When a file changes, it is
deleted from the backup set, freeing up room for new
and changed files.  Fastback backup sets grow each time
you preform an incremental backup.  DiskFit backup sets
only grow as the data on your hard disk grows.  



The differences between the two programs raise
several issues:



1.  How many backup sets do you wish to maintain?  If
you want to keep multiple backups, then DiskFit might
make more sense because you won't have to keep adding
floppies each day to each set you back up to.  I
personally do not trust my data to only one set of
floppies because the data is only as safe as the floppy
is reliable.



2.  How important is it to you to keep old versions of
files in your backup?  DiskFit removes old copies of
files from your backup, and Fastback adds new and
changed documents to the end.



3.  Regarding speed:  Fastback has a faster short-term
backup speed, but from time to time you are forced to
perform a complete backup from scratch because your
set grows too large.  With DiskFit, the set sizes remain
stable, so you do not have to rebuild them.



These are some of the issues you should consider when
deciding what backup program to purchase.  I have an
obvious bias towards DiskFit since I work at the
company that created it.
