Your Computer

Estimates put the value of the data on a computer three months old as being of more value than the cost of the hardware. When next you need to replace your computer, get the vendor to put in two mirrored hard drives so if one fails all your data is on the other drive.
Next step is to get at least one, if not two, hard drives so you can copy the data from your computer to one of the drives then give it to a trusted person to store in an off site location. Put a password on the drive so that if the trust sours, your data doesn’t become public domain.
