Armory - newbie - paper backup basics?

[candtalan]

Just started using armory (on top of satoshi), a single armory wallet containing one address from a received value from my satoshi wallet, and after confirmations, I made a paper backup. It all worked :-)
However, I subsequently transferred another additional address value (is this a correct description??) into the armory wallet, and when confirmed, I decided to again print out a paper backup.
I am mystified that the first paper backup of the armory wallet appears to be identical numbers as the second paper backup, because in the second situation, the wallet contents was different (increased). What have I missed here?

The paper backup contains no information about the # of bitcoin in each address. It only encodes information to recreate all current and future private keys and public addresses. Armory uses "deterministic wallets," meaning that any time you recreate your wallet from a paper backup it will generate the identical sequence of private keys and public addresses.

Any bitcoin you add to your wallet will appear in a wallet restored from a paper backup.

I made a sticky to talk about backups:

This is one of the main reasons people use Armory:  you only need to backup one time, ever.  Period.  All your addresses are generated from the data on that paper backup.  Every time you receive coins, it just gets the next address in the mathematical chain of addresses.

All addresses are seemingly-unrelated unless they have your wallet.

Thanks for the responses.
Wow. Freaky stuff.
;-)

Does it follow then, that if I create another, new, armory wallet, alongside the first armory wallet, and transfer the contents of the first wallet into the second, (maybe even delete the empty first wallet) that only the backup of the second wallet is relevant, and the backup of the first wallet is of no security value to anyone?

When you say "transfer the contents", I assume you mean "send the coins" from one wallet to the other...?

In that case, yes.  If a wallet has no coins left, and you are not expecting anyone else to send any coins to any of the addresses in that wallet, then you can safely discard that wallet.

Does this backup include 'change' addresses?

Thank you!

Thank you!

All addresses you ever generate in your wallet are all derived from that root key and chaincode.  Change address is chosen by just picking the next unused address in the sequence.  For instance, if you have received Bitcoins to addresses 1-10, then you send a transaction it will use address 11 as the change address, then address 12 will be the next one to pop up when you click "Receive Bitcoins".

Thank you very much etotheipi!
