Hi,

I know wallet.dat is the key thing I need to not lose or have copied.

If you are concerned about protecting from loss, the wallet.dat is all that is needed to have the ability to spend the funds. If you use wallet encryption, all that is encrypted are the private keys held in the wallet. Addresses and transactions are not kept private in that file even with "passphrase protected wallet encryption".

Now if you are concerned about privacy, there is leakage of address and transaction data in the log files. This is because BDB (database storage) writes this in case it is needed for automated database recovery should the app crash or proper shutdown not occur.

So if you don't want traces of your activity to exist on your system, you might want to use a TrueCrypt volume or an encrypted filesystem.
