Get a 'caddy' - a USB case to take a Seagate or Maxtor hard drive. Plug it in, format it and away you go. XP Pro has a built-in backup utility which will allow you to do a full system backup which can be used to restore your OS in case of failure via the Restore Consol (it's available in XP home but it's 'hidden'). For incremental back-ups of personal files try EZ Backitup, a free download or on many PCA discs.
