Yes but (a) easily is a big word. it depends on what you backup, otherwise backup strategies are not that trivial.
(b) it is still an additional work.

Exactly this is the not easy issue. Depending on the format you should keep along the programs, that may not work or may get corrupted. Aside from plain text (that still may not work due to possible encoding changes) , I really don't know anything that is very stable on digital files.

Unless there is a backup software built to be used in the future and be compiled over and over. That's quite a project thought.
