I read on wiki it says that you can only backup 100 key of Bitcoin-QT.. if you have more then that some of the Bitcoin would be lost..

Can anybody explain and probably come out with a solution if I want to have 110 keys? If you are really curious you can ask me why I need so much key Smiley

Without a link to this wiki page, you certainly misread it. There is a pool of keys, which defaults to 100 keys. Bitcoins don't get lost, but you need to make another backup after refilling the pool because now you will be receiving keys from this pool which you don't have a backup yet. You need "so much key" because it is how the client works, you get new ones on completed transactions.

If you want a pool of 110 keys, pass -keypool=110.

I don't know if I get you right, you are saying that after getting more then 100 keys I just do another backup and I am safe? and for the command -keypool=110 it is just to unlock so that I can get more then 100 key?

Yup, with default wallet, you need to back it up every 100 transactions. The new backup will obviously contain all keys since wallet's creation.

Thanks, now I know I need to backup once in a while (every 100 keys). The explanation on wiki was quite confuse at first...

Basically you have 100 pre-generated addresses in your wallet and you use them when you create an address or send a transaction.  As long as you haven't used all 100 of these addresses since your last backup it will still be valid.

To increase the number of pre-generated addresses in your wallet, add keypool=number_of_keys_you_want to your bitcoin.conf file or run bitcoin with the previously mentioned command line option.
