BACKUP SOFTWARE-BASED ENCRYPTION

While encrypting data "at the tape" can offer some compelling advantages, you will need to upgrade the tape drives themselves, update device drivers, change drive settings in your backup software and switch over to new media. The impact on your existing backup process can be substantial. Many organizations choose instead to implement encryption in the backup software running on a backup server. This segment will focus on specific considerations for software-based encryption products.

BACKUP HARDWARE-BASED ENCRYPTION

Encryption appliances sit inline on a network and use specially designed electronics to encrypt data at line speeds, essentially eliminating the performance penalty imposed by encryption software running on a general server. While software-based encryption is typically handled as a specific event or process (e.g., encrypting data during a backup process), appliance-based encryption normally can handle any quantity of data in flight.
