Backups tapes a backdoor for identity thieves
Robert Lemos, SecurityFocus 2005-04-28

In many cases, low paid workers are handling sensitive tapes, but only a small fraction of companies are securing the data with encryption.

Your crypto is old and slow! 2005-05-06

"a standard cpu will manage somewhere around 1-10Mbps - significantly less than the throughput of tape drives and networks."

Optimised modern crypto can do much better than that. Reasonably good implementations of RC4 on a 32 bit, 1.8 GHz machine do around 150 MB/s. That's B, not b, in other words 1.3 Gbps in networking terms. Should tuck your 500 GB database away in a little under an hour, if the network can keep up. There's no tape drive that comes close, the fastest are about 140 GB/hr (40 MB/s) -- and those cost around US $30-40 thousand, about twenty times as much as the PC !!

If for some reason that's not good enough, IBM (for one) already have an FPGA implementation of AES that does 11 Gbps.
