Upgrading from Catalina to Big Sur
I'm terrified of upgrading OS because it's such a pain to backup data. Is there an easy way? And how do I retrieve it?
MacBook Air 13″, macOS 10.15

Backing up using Time Machine is fairly easy. See: Back up your Mac with Time Machine - Apple Support
I use an external USB SSD but the following covers the options: Backup disks you can use with Time Machine - Apple Support
