Encryption can be a drag.
A combination of regulatory and legal pressures and a healthy fear of data loss or theft is driving many organizations to encrypt their backup tapes these days. But adding encryption can slow performance, even with high-speed LTO-3 tape drives.
Enter NeoScale Systems Inc. , which tomorrow will roll out a new encryption software suite for its CryptoStor Tape storage appliance. The vendor claims the add-on to its system, which encrypts data via a security appliance as it streams onto the tape drive, reduces backup and recovery windows for tape drives substantially.
"We're optimizing our software so the tape drive can deliver the same performance it would get when it didn't have us in the picture," says Dore Rosenblum, vice president of marketing for NeoScale.
While LTO-3 tape technology runs at 80 MByte/s natively, encryption can slow that down significantly. Though hardware-based storage encryption devices like NeoScale's are supposed to perform better than software, there is still a performance tradeoff.

With the move to the cloud, CISOs must shift priorities from operating security programs to overseeing (monitoring and auditing) outsourced cybersecurity programs.
2022 was a boon year for IT salaries. 2023 came in like a beast with layoffs, raise freezes, and ChatGPT, but that beast has few teeth.
