Angela is considering using encryption as part of the security controls applied to her backups. In the event of a major disaster, what concern should she address about having encrypted backups?

A primary concern for organizations that encrypt their backups is whether the keys are available in a disaster. Ensuring that the keys are stored in a manner that ensures that they are recoverable if the backups are recoverable is critical. Modern backup encryption typically does not add a meaningful amount of time to backups, nor does it increase cost or space to such a significant degree that it is a primary concern.
