Time Machine, Apple’s popular backup app, isn’t limited to working with backup volumes that are physically attached to your Mac. It supports remote backup drives in the form of networked drives, including Apple’s own Time Capsule product.

Network-based Time Machine volumes are very useful. Having your backup drive in a remote location, one that’s physically isolated from your Mac, protects your backups in the event your Mac has a catastrophic failure.
Another wonderful use for remote Time Machine volumes, such as Time Capsules or NAS (Network Attached Storage), is to allow multiple Macs to perform backups to a single central location.
