As good as that advice is, and as general as it is, I can't think of a
single one of my customers to whom it would apply WRT WHS. To them,
it's going to be another computer, with all of its associated costs
including acquisition,
As I said, $200-300. It's not nothing, but it's not a fortune either.
And it also does multiple computers. I have it doing three here.
Tiny. Just a few dollars a year.
and system administration.
Next to nothing. You set it to do backups and you hardly ever have to
look at it again, unless you need to do a restore from it.
It's a hard sell, which brings us back around to the question of why
so few people use it.
So few people use it for several reasons:
1. Most people don't even know it exists.
2. The people who know it exists know next to nothing about its
capabilities, and how easy it is to use.
3. Very few people know that it can completely automate the backup
process, for very few dollars, and with very little effort on their
part.
4. Many people have very little to backup and what they do have to
backup gets changed so little that it seldom needs to be backed up.
For such people, automatic backup every night would be overkill. For
example, I have a friend who backs up everything she needs to by
simply copying it to a thumb drive once a month. For her usage, that's
fine.
5. And with respect to your calling it a "hard sell," I suspect that
you don't do a good-enough job of trying to sell it--perhaps because
you don't use it yourself, and don't know enough about it. Start out
by saying "how would you like to have a completely automated way to
back up everything on all your computers every night for a one-time
cost of only $300" and you might get a very different response.
And by the way, unlike what kreed says above, I don't think it is
"definitely the best option" for everyone with more than one computer.
People have different needs, and what's best for one person isn't best
for everyone (see, for example, my point number 4, above). But I do
think it's a good choice for many people, and we should all do a
better job of telling people about it and having them consider it as a
choice.
