I don't know yet the details of how a wallet looks like internally,
but I think it should be possible to print the wallet incl. acct nbr
out on classical paper (as base16 or base64 etc.) for filing it
in a physical home or bank safe.

Later, typing it from paper to a small converter program that recreates the 
wallet file.

IMO this is a good security against possible computer hardware disasters.

Of course one has to secure this further with encryption against bank 
fraud/theft etc.
Ie. the output on paper should be encrypted, and the owner
should place the key somewhere else.

I would suggest the developers make such functionality available for the user.

Bitcoin Core still does not support Hierarchical Deterministic aka BIP32
Wallets. Without them it is possible to backup just one private key per
backup, which is rather useless and in fact dangerous.

I would suggest looking at different software wallets that do support
such functionality such as Electrum or Multibit.
