I could relate this in the past.
Not my experience but there are a lot of people who bought Bitcoin and are not serious about holding it or trading it and when the price exploded, they are posting everywhere asking about how they would be able to get back their wallets with their private keys gone, forgotten, and deleted. Some even already threw their PCs where their bitcoin is stored.
It takes just 5-10 minutes to generate the backup file and to store it securely. This could save you from potential heartburn later. During the early days, a lot of people lost their coin holdings to carelessness. I still remember reading about an incident, in which an user lost 25,000 BTC in 2012, because he didn't bothered to enable email confirmation and 2FA to his Bitcoin wallet.
