Essentially, any way to store information is a way to store private keys.

Bitcoins aren't actually themselves stored anywhere.

What you need to store is a private key that the bitcoin network says has coins associated with it.

That private key is just a string of data, That can be stored anywhere data can be stored.

Yes; I know that.

Here are some of my favourites:

1) Floppy disks both the 3.5in and 5.25in variety. I have not tried it with 8in floppies yet    Wallet.dat will easily fit on a 3.5in or 5.25 in floppy disk even the old 360 KB 5.25in floppies. With 8in floppies in principle it could be done with a carefully constructed wallet.dat small enough to fit on an 8in floppy. The more the better. Rename the file extension to something innocuous such as an obscure propriety Windows word processing program. Also consider changing the last changed date on the file to a date before Gavin was born.
2) USB 3.0 external hard drives. Ironically I have not used USB 2.0 devices to back up my BTC.
3) Encrypt the file with Truecrypt or some other encryption program. Then store the cypher-text file on multiple cloud services such as Google, Live / Hotmail, Ubuntu One, MEGA etc. The more the better. Diversify across multiple jurisdictions Rename the file extension to something innocuous such as an obscure propriety Windows word processing program.
4) (1) and (2) with the floppy and / or USB external drive stored away from your home, such as bank safety deposit box, car, friend or relative, workplace etc.
5) Back up the encrypted cypher-text file across multiple computers, laptops tablets, smart-phones  etc. Include all computers and devices you regularly use. If malware is a concern for example a Microsoft Windows computer, do not decrypt the file on that computer or transfer the file back to a computer where the coins can be spent except as a last resort where all other backups have failed.  Also include old and vintage computers if you have them, these are an excellent for this purpose. How many current bitcoin stealing malware applications run on a 286 processor or on an old Windows 3.1 computer?

The idea is to be able to access your BTC in all sorts of scenarios ranging from a simple hard disk failure to having to flee your home, city and even country with nothing but the shirt on your back.


*** Very Important ***

Last but not least ensure that your loved ones / and or executors of your estate can access your BTC after your demise in all sorts of scenarios ranging from a simple hard disk failure to having to flee their homes, cities and even countries with nothing but their shirts on their backs.

How many places can you think to store a short string of numbers?

Convert to binary, make a binary painting for your wall.
Tattoo.
Write it in the wet cement of the foundation of your house before building it.
Piece of paper in a safe deposit box.
Hidden in a jpeg.
E-mail it to yourself through "future me".
Etch it into something you wear, ring, dog collars, necklace, etc.

That was helpful, thanks.  I use Truecrypt, but I don't like it--too complicated--things like 'mount' and 'dismount' are sort of alien, I wouldn't be able to teach my family that very easily.  That it's open source is good though.

Plus, I'm paranoid that I'm somehow screwing up whenever I overwrite the old wallet!

Got a new one:

Use PySkein then http://pythonhosted.org/pyskein/ it was a NIST3 finalist and designed by Bruce Schneier and some other ppl. "pyskein threefish encrypt <filename>"   "pyskein threefish decrypt <filename>"

It produces a copy called wallet.dat.3f and leaves the original untouched if you want, or encrypts the original depending on your settings. I use it to encrypt 1 TB Virtualbox .VDI drives of software I'm working on and it flies compared to SHA256 AES.

Never knew you could store BTC on floppy dicks.

NFC tags, ala: https://www.bitmit.net/en/item/20612-3d-printed-nfc-enabled-bitcoin-simulacra

Morse code memorized for whistling, and passed on from one generation to the next. I know, it;s just another form of brainwallet, and a retarded one for that matter.

I think you'd have a problem with capitals letters using morse code.  It may not provide the highest security, but I bet you won't loose it if you mow it into your lawn like these people did (just make sure it's encrypted):

RAR your latest or updated wallet.dat file with 10% recovery record, and your nice long 30 character password. Install Dropbox in 20 computers, tablets, phones, ipods, etc. Sync. Email it to yourself.

For physical storage, embroider the private key on a piece of cloth, then stitch it under your shirt where it is not seen, or on the pockets or pants or other clothes you wear.

Get a money belt, they have spaces to hide real money, should be no problem to hide little pieces of laminated paper with your private keys.

Dog Tag.

Physical photo album. Hide it behind some pictures.

Handwritten in an old book. Use black oil based ink, not those water based ones. Optionally paint over it with clear nail polish.

Carve it into a wood sculpture. Or just plain carve it into anything wooden, like under you baby's crib or something.

Make some pottery statue with the private key inside, then seal it shut. They do this with drugs like in the series Lost.

Hide it in a hollowed out wax candle. Then melt the cover with more wax so it is also sealed.

Time capsule.

Engrave it on your gun (if you are into firearms). They will get your bitcoins when they pry your gun from your cold dead hands.
