[CentOS] Backup PC or other solution

I list,
I'm new with backup ops and I'm searching a good system to accomplish this
work. I know that on centos there are  bacula and amanda but they are too
tape oriented. Another is that they are very powerfull but more complex. I
need a solution for small office for disk storage and I found Backup PC.
Many people say that it is great for small stuff and for great number of
data.

What do you mean about Backup PC?
Any experiences?
What solution do you use?

Thanks in advances.
