Not having experience with either SCO or FP on Linux I can only answer 6.

I moved from using tapes to creating "snapshots" of my data on an 
off-site storage unit.  (My data is served up by a Samba server.)

Rsnapshot (http://rsnapshot.org/) uses rsync and symlinks to create 
snapshots of your system and data going back to any number of hourly, 
daily, weekly, etc.  It does this efficiently with symlinks so that only 
changed files are stored.  If a file doesn't change then you simply 
create a link to the existing file.  Rsync efficiently makes the 
transfer of only the changes to a file.

I did it 3 years ago with a hack of a $90 D-Link NAS device that is 
still running.  Today I'd probably do it with a Synology device.  (I 
think that they have a version of Time-Shift working on their system.)  
I'd also set up a local backup in case I have to restore a large amount 
of data quickly.

I used to have regular problems with tapes.  I haven't had a single 
problem recovering data from the new setup.
