Copy SMS messages in real time?

[Dream]

Is there a program or a way to make a copy of the sent and received SMS messages in real time, without scheduling or manually creating a backup? If so, would you be able to have the copy saved to the storage card?

What I'm looking for is when I send or receive a text message, it will automatically save that message on my phone in the standard cemail.vol file as well as another specified file on my storage card. That way, if I accidentally delete the message I will still have it on my storage card.

I'm not sure if this is even possible. Thanks.
