Very true.

However, backups are not just made in case of hacking - they are also made
for disaster recovery.
In a commercial environment, you should be sure that you can bring back your
web and file servers from a complete hardware crash  - or even theft of
equipment.

It is a good idea to brainstorm on this with your colleagues,
and practise a rebuild/restore of your server on similar hardware.
Your bosses will be reassured when you can answer them truthfully, and give
a real estimate of how long a restore will take.
