No problem... there's plenty of good encryption software available :-).

But anything less than full guarantees on bandwidth, availability,
and reliability makes an offsite backup provider worthless. Even to a
"hobbyist", the value drops very quickly if you can't completely trust the
provider. Real data centers have high-reliability hardware, redundancy,
backup power, physical security, and lots of other goodies that help
make the service expensive.
