Having a backup is always a smart idea, but it is essential to remember that there are different levels of backup that a business can implement. It’s one thing to be protected against a server crash; it’s quite another to be protected against a disaster that destroys your servers, as well as those of every business within a five-block radius. While local backups serve a purpose, they cannot be the only thing you rely on. Real resilience means looking elsewhere to achieve redundancy.
