how do you back up data on your home computer?

Grandfather-father-son backup schemes is an old rule of thumb many
people used to use, including myself. Been around as long as I have been
in the industry. As does David Hummel I use rsnapshot. The nice thing
about rsnapshot is that you can keep arechives for months, but it only
stores new data when it changes. So, if you have a file that is months
old, you will only have 1 copy on your backup set with 1 hard link for
each directory it is in (such as hourly.0, hourly.1,... daily.0,...).
In the old world of tape backups, we would use the rotation scheme.
Today, what I would do in a commercial installation would be to maintain
a convenient physical backup available online, and maybe one or 2
physical backups offsite or possibly use an online backup service.
