Data Encryption for backups. Wow…what
a topic. We've tried doing encryption via Netbackup and the tape backup
performance went from 60MB/s per tape drive to 6MB/s per tape drive. No central
key management and required manual tracking of encryption keys. Software-based encryption is going to suck for performance. CPUs get faster, but then encryption routines have to get more complex so it's a never-ending battle. For a small subset of data, client-side encryption might be acceptable, but in general, don't use software encryption (or compression).
We've got multiple Decru appliances and we can top out writing over 100MB/sec. As long as you don't saturate the appliances - and I believe the practical limit is 2 LTO-3 drives per FC520 - encryption is nearly a realtime operation.
