I disagree a bit. Some things might require long-term data storage. For example, GPG keys, personal wallets, private documents and certificates.
Imagine how much of your life can be wiped out by a Carrington Event, which is not that unlikely.
I don't trust clouds for this. Right now, archival-grade DVDs are not a bad option. Almost 5 GB, and under good storage conditions these can last >50 years, probably more.
