Backing up your Mac is an absolute necessity, not just a beta-testing ritual. Apple's Time Machine offers a built-in, relatively simple solution, automatically creating backups to an external drive. However, it's critically flawed: it's notoriously slow and lacks tools to verify backup health. Crucially, Time Machine won't help if your Mac itself fails, as it only backs up data, not the operating system.

This means users remain vulnerable to catastrophic hardware failure without a bootable backup solution. SuperDuper! 3.10 at $27.95 provides a robust alternative, capable of creating bootable external drives, though it requires manual management.
