Option to create a daedalus wallet backup?

Do users of Daedalus windows wallet need to save a backup of the wallet? like in other wallets users can make a backup and have the wallet.dat file under the roaming folder, but in this daedalus wallet at roaming under wallets folder, I only saw 3 different files and not sure which one is the backup wallet.

I’d just backup the whole folder C:\Users>user>\AppData\Roaming\Daedalus Mainnet to be sure I have everything required.
