There is so many guides and even youtube videos about this that it is confusing.
This is the way that I secured my wallet:

Running a Live Linux Encrypted Distro and encrypted my wallets offline.
Copy it to an USB Drive
Take the USB Drive to another computer copy the wallet.dat to it and send it to my email.
Storing the wallet.dat on my phone, another computers and even the email as it.
The files are secure?
I can see that for make transactions it's need my password.
I still have doubts about keys. I have to read about it.
And about backing up the wallet?
If I do this:
1. bitcoind -daemon
2. bitcoin-cli backupwallet wallet_bak.dat
The wallet_bak.dat of the encrypted original wallet.dat is also encrypted?
Or do I have to run gpg on it?

Distros, backup, email, computer is a bit complicated if you ask me. What I just did, bought a cheap hardware wallet (only from the manufacturer website, never trust other online stores) , set it up on Linux machine, saved a copy of the 24 words seeds in a secure RAR file protected with 65 characters password and uploaded this file to my email with 2FA (i.e google mail). I always use the hardware wallet and I don't keep backups. If it happens that my hardware wallet breaks, I can always buy a new one and restore it with the 24 words seed.
Cost of this is only 0.025 BTC (actually with bitcoin price at all time high, it's a bit less).
Why complicate life for just 0.025 BTC ?
+ 1 for hardware wallets.
In balance though, I am glad I went a few years before going to a hardware wallet. I spent lots of hours learning Electrum, cold and hot wallets, etc..... All this didn't make me more secure, but it taught me alot about the blockchain and how it all works. TX's, taint, etc..... So grab a hardware wallet and be immediately secure, but still learn the BTC environment for fun or a business.
