I use Truecrypt on two 1Tb usb-drives in order to keep a backup for all my files. One stays with me, one backup is left in another place, in the hands of a friend. I don't have to worry about someone reading the content, f.i. if it would be stolen. I can use my regular backup-software (Dsynchronize, also free) on the encrypted disks. On my network drive (NAS) I have created a safe container that mounts as a drive in order to keep my kids away from personal sensitive date (bank accounts and so on). To end with: all my professional data is kept separately on a encrypted 320Gb mini-usb-drive, perfectly save to take with me in the car, in the buro, on a day-to-day basis. If stolen, it would be a small disaster, but not a big issue.
Until now, this software works great, I encountered no errors whatever.
