I haven't tried that one, sounds interesting with the backups.
I will look it up :)

Can vouch Electrum is a solid choice, Electrum works via a seed which is a string of random words used when generating your private key during wallet creation. As long as you remember the seed you have access to your funds. They also have a private key export option but I would suggest encrypting the resultant file after exporting for maximal security. :)

It's so important to have your investments in a safe place.
Thanks for the info @nphacker :)
