Ralph,

SuperMac Software's Network DiskFit will allow you to backup any AppleShare or
TOPS fileservers, but we don't recommend backup up an entire server over the
network for 4 reasons:

1.  Speed.  AppleTalk is much slower than the file server's direct hard disk
    connection using the SCSI port.  Therefore, backups are much slower.

2.  Network use.  The AppleTalk network is used for a variety of purposes.
    Backing up over the network reduces its performance for everyone else.

3.  Files that you do not have read access to will not be backed up.  It would
    be necessary to provide a "backup group" and make sure that everyone on the
    server caused all folders to belong to this group.
4.  Information on onwership and access priviledges is stored only on the
    AppleShare's direct connect hard disk.  That information would have to be
    recreated by the network administrator after restoring.

Note that the above was for backing up the entire server over the network.

Network DiskFit allows you to create a SmartSet over the network of files
stored on an AppleShare file server.  You are given the option to back up only
those files that you own as opposed to all that you have access to.  If you
create a Visible Files SmartSet, all files that Network DiskFit can read will
be copied to the SmartSet.  These will be all of the files accessible to you
in the Finder.

If you create an Owned Files SmartSet, only those files contained in folders
that you own will be copied
Essentially, Network DiskFit must be able to read a file to copy it to a
SmartSet.

Network DiskFit allows you to back up mounted HFS TOPS volumes in several way:
to another mounted HFS volume, or to a SmartSet.

Network DiskFit is a multi-launch application and a site license of up to 32
users on one contiguous AppleTalk network is included in the suggested retail
price of $395.

Network DiskFit (as does DiskFit) will allow you to back up to diskettes,
another hard disk, DTC/Kodak cartridges, Bernoulli cartridges, Syquest
cartridges, and any DC2000 tape drive that uses the 3M controller (SuperMac,
Apple, and GCC).
