  • Page 48: Does Encryption Affect Tape Drive Performance

    WARNING! You should keep a record or backup of your encryption keys and store them in a secure place separate from the computer running the backup software. Not even data recovery services will be able to recover encrypted data without the key! Does encryption affect tape drive performance? Hardware encryption can be used with or without compression and without speed or capacity penalties.
