Disk Encryption with TrueCrypt and Backups

[Neil Jones]

Most companies these days are using disk encryption on their laptops. I
am planning to use TrueCrypt for my laptop. The question I have now is
about backups and the system restore procedures.

I do my backups to an external disk and am assuming that the complete
system backup is also going to be an encrypted image. My main concern
is about the restore session. If I do have to restore my laptop from
the backup, then how does the disk encryption crypto tools such as
TrueCrypt work?

Thank you in advance for any information.

I use TrueCrypt with a pair of Iomega eGo USB2-powered drives and Second
Copy which replicates my C drive to the eGo. I have found this equally
successful when encrypting the whole eGo or just a volume on it. Once the
drive is mounted and the (very strong) password entered, the data on the
encrypted drive behaves exactly the same as if it had not been encrypted.
Incremental backups work fine and I have had occasion to retrieve data after
a hard drive failure. I swap the portable drives weekly, one of them always
being off site in the boot of my car and the other in a different part of my
house except, of course, when I am backing up. These drives are robust and
yet so cheap that they can almost be regarded as consumables, so having one
for each day of the week might be considered.
