Z-cash: what's a proper way to backup your wallet?

[GTCG]

Hi everyone,

I'm a bit confused of how to backup my Z-cash wallet. I've done the following so far, but I am unsure if this is enough:

- Generated a T and Z-address on the Z-cash network
- Wrote down both these addresses, together with their respective private keys
- made a backup of my zcash.conf file, which contains my login and password to connect to the Zcash-network

If my system would crash I would reinstall everything, import both T and Z addresses together with the private keys and reinstall the zcash.conf file.

What I'm wondering about:

- There is also a file called "wallet.dat" on my system. Do I need this file as well? Or is it actually the only file I need to backup my wallet? I have seen you can import this file as well with zcash-cli...
- What about the username and password in the zcash.conf file? Do I need to use the exact same username and password if my system crashes and I have to restart from scratch? What exact purpose do the username and password have?

Better to backup all files to be sure you will have access to wallet if pc is broken
