Buy an external drive, save all of your precious files, and store the drive in a safe, only to be used in emergencies.
Burning discs is another. I admit that I have countless burned disc in storage and doubt that I have looked at hardly any of them.
I have three 2-TB external drives that I occasionally do my backups to... and keep them in a drawer when not in use. I also have three older 1-TB drives with older backups on them.
When I moved cross-country a year ago I mailed one drive, put one on the moving truck and carried the third one with me on the plane. Never can be too careful with my stuff (mostly photos).
