Some wallets such as Electrum, Sparrow, Bitcoin Core and Schildbach wallet have a functionality to import/export encrypted backups with your wallet's encryption password, and this is very interesting, as in addition to being done in a theoretically safe way, you don't need to resort to other third-party encryption methods that may compromise your seedphrase. With this encrypted digital backup, you can easily make multiple copies and spread them to different locations such as pen drives, SD cards and the cloud.
Making an encrypted digital backup is safe if the password is secure, but making several copies and publishing them online or uploading them to the cloud is not a good thing. So, if you use a strong password, you will definitely keep it in digital form, so reduce the number of online copies and keep the password on a separate device that does not connect to the Internet. Buy a high-quality USB stick to ensure a longer lifespan of data on a USB flash drive and better protection from shocks, as some bad types lose the data within 5 years.
