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?
