I know I am going against the trend as everyone is talking about using HD as a 
backup device, but we are looking as something "my life will depend on". If we 
were to loose data, we would end up with a multi-million dollars law suit and 
we'll just go bankrupt.

As we are a SAAS solution, everything is already redundant, we can drop a plane 
in one of our datacenter and customer won't even notice (technically speaking) 
as everything is load balanced and replicated live across the sites.

We have very high security with loadbalancers, IDS, DDOS protection, etc.

But let say a hacker would manage to get in and play around, or even an angry 
employee, or...
A simple "rm -r /" and all of our protection is gone. Our 2 distant copies and 
the zfs snapshots also...

It's kinda hard for a hacker to format all the tapes in a library furthermore, 
some tapes will be put in a safe...

I love the idea of using HD, so simple, cheap and fast, but if you need 
absolute peace of mind, I think a tape backup is much more reliable in this 
sense in my opinion.

That's why I'm trying to see if bacula could be a good solution in our scenario.

Thanks
