Don't store your history on other people's computers. Ask yourself what you would pay to get your data back if it were suddenly destroyed.
Invest in a backup drive and use it, so you always have at least 2 copies of what you care about. Storage is cheaper than ever.
Seagate 1TB for $70 USD, for example, or Toshiba 2TB for $80.
@skry No joke - last month I lost ALL my old scanned photos, wedding photos, old family photos in an accidental delete. If I didn't have that backup, I'd have lost 100+ years of memories.
@inkican Wow. That's terrifying. Good for you!
