… is a necessary rule of thumb for computer-based knowledge & design workers. But add the lesson of cloud computing:
Backups: If you don't have 3 copies, you aren't serious.
The standard redundancy for cheap cloud storage options is 3 copies. Anything less is reduced redundancy, sold at discount. You should have at least 2 backups, for instance both a home backup disk and a cloud drive or repo.
