What the man from Bracknell said.
What I was trying to say is that
Groundbased worded his message in a way that implied backups were an important means of recovering access to your encrypted data.
What I was trying to put forwards is that whether or not you encrypt your data doesn't come into it in terms of the importance of backups.
Backups are a fundamental part of IT, irrespective of whether or not encryption is deployed.
i.e. you should already have a backup regime in place prior to deploying encryption, not as a result of deploying it.
Capiche ?
