How to backup bitcoin wallet

I am news user and have questions
I know Lightning Network page has option for saving channels - “Download channel backup file”
But how to backup and download Bitcoin wallet? There is no options

your seed. that’s it

ohhhh you right!

What about lightening wallet?

never heard about “lightening” wallet.

But if you refer to LN wallet it is also mentioned in there how to do it. Read more careful.

yes i meant LN wallet
Didn’t found any information
Is it enough ““Download channel backup file””?

YES! This is the way. And save it in a safe place.
Get used to do that backup EVERY TIME you open or close a LN channel.

thank you!
