BlueScale Encryption Editions
BlueScale Standard Edition:
For sites with a primary goal of securing data while it is
transported to a remote site and stored there, or only for data that will be stored for a long
period of time, BlueScale Standard Edition works well. Standard edition lets you store one key
on the library at a time.
For information about configuring and using BlueScale Standard Edition, see
Chapter 8. Using
Standard Edition in Spectra T50 Libraries
.
BlueScale Professional Edition:
For sites that want with greater flexibility and security, to
protect data wherever it’s stored and regardless of the retention period, BlueScale
Professional Edition works well. Professional edition provides additional security features,
and permits the use of multiple keys on the library at single time.
For information about configuring and using BlueScale Professional Edition, see
Chapter 9.

Encryption
Login
Passwords
• Single encryption password
• Easier to manage and track
• Choice of either one encryption password or three
• More secure, with the option of requiring multiple
users to export and import keys, etc.
Key Export
and Import
• Import and export functions require
a single password, so easier to
manage
• Choice of a single password or M-of-N shares with
multiple passwords to export/import keys
• More secure
Compatibility
between
versions
• Data encrypted using either version can be decrypted by a library running the other version.
• Data encrypted and compressed by a library using drive-based encryption and running
Standard Edition can be decrypted and decompressed using Professional Edition. LTO-4
drives natively compress data while encrypting it. Standard Edition through the QIP does
not support compression.
Summary
Less secure, but less to manage
More secure, but more to manage
