Does a wallet in blockchain.info My Wallet contain a pool of extra keys as in bitcoin-qt?

Should the wallet be backed up after every new address is created, or only after several are created?

    A duplicate all right. Now why didn't I find it in search? Edited a bit the other question. Feb 10 '13 at 19:31

It doesn't (or, at least, didn't).

Email backups will be sent to you every time you create a new address.
