How do I back up my Kaspa CLI wallet?

To back up your Kaspa CLI wallet, locate your keys.json file at %localappdata%\Kaspawallet\kaspa-mainnet and copy it — along with its password — to a safe place. The keys.json file is the only record of your wallet's private keys; if you lose it without a backup, you lose access to your KAS permanently. The source recommends making two or more separate copies on different media, such as a backup hard drive, an encrypted flash drive, or cloud storage. Having multiple copies in different physical locations protects you if one device fails, is lost, or is damaged.
