GEdit can make backups of files that have already been saved once.

But can it make backups of files that I have just created, and not saved yet?

Those files are typically shown as "Untitled Document 1" etc.

Motivation: I often create new text files to quickly write a phone number or something, and Ubuntu 2012.04 crashes quite often, so I end up loosing information sometimes.

If GEdit can not do this, is there a similar, fast-to-start program that has this feature?
