I understand you can backup your wallet.dat file and save it on a usb. Does it save all your future transactions you continue to do on the client program or do you have to keep backing up the wallet.dat file everytime you make a transaction. Hope it makes sense.
Thanks.
Yes, you DO need to back up once in a while.... new addresses are created behind the scenes when you spend and the client keeps about 100 spares at all times... so after 100 sends your wallet would be out of date
