Now that I have updated my iDrive I notice what looks like an extremely useful local backup facility. However, what I do not want is an encrypted local backup. I'd like it unencrypted for two reasons.
1) I'm the only user of my PC and I backup to my external HD or a USB stick. There would be no particular advantage in having encrypted information on a device sitting next door to the PC containing the same information unencrypted.
2) More seriously, if my PC suffered a major breakdown (and I've had enough to know that the risk is not insignificant) then I'd be locked out of my information until I replaced the damaged system or found someone willing to put iDrive on their PC. Plus there's always Murphy's law and I end up finding problems in decrypting the information on a new PC.
