Backup of a wallet

[Blau]

I have encrypted my wallet file with 7zip and uploaded to my cloud; and i will use the same wallet for next transactions. If my computer lost, would i able to use my coins? The backup is old, and doesn't include new bitcoin addresses created by Electrum afterwards.

If your computer gets lost you would still be able to use your coins by using your backup wallet. However you should also back up your wallet words that you created your wallet with. They are all you need to restore your original wallet. You can choose to only backup your wallet file, but it's safer to also backup your wallet words.

New Bitcoin addresses created by Electrum after you backed up your wallet will be available if you restore from the backup. Electrum can generate millions of them using your old wallet file. Each wallet file will always generate the same list of addresses.

Yeah, best to just backup your seed words as you can restore your wallet from those alone. Just make sure that you store them somewhere safe and encrypted. Storing them in the cloud probably isn't the best place to store seed words.

Why did you encrypt it with 7zip? Electrum already offers you an encryption, if you want to encrypt with 7zip at least make sure to encrypt your wallet by setting a password on it and then use 7zip.
also make sure you use AES-256 on it in 7zip (not sure how strong the other option is)
and also make sure to use a strong password not simple stuff such as "qwerty"

I have also encrypted my wallet in Electrum, two is better than one I found that all .7z archive files which are encrypted use AES-256, so there should be no breach. I added my seed to the archive and changed the password with very strong one (like 16 numbers and 9 letters).

Thank you guys for your explanatory answers.

yep. btw just setting a password on the wallet encrypts the seed in the wallet file so there is no need to encrypt it again with 7zip.
