[ale] tape backup of homenet

[Frank Zamenski]

Dow,

Thank you for the detailed information and the script. It is a good starting
point.
I would tend to agree that just reloading the MS OS would likely be a safer
choice. I know many shops will just backup the MS registries only in
addition to
the data, for those times when MS workstations [finally] flake out.

I'm not familiar with DDS3 drives, are these within the 'affordabilty range'
of the
typical home network ($500 +/-)?

Thanks again.
Frank
