Leopard

OS [X]

One of the key features of Time Capsule is the ability to back up a system and files wirelessly and automatically, eliminating the need to attach an external backup drive. This feature requires OS X 10.5.2 Leopard or greater on the client computers. The backup software is Apple's Time Machine, which, by default, makes hourly images of the files that are being changed, and condenses backup images as they become older, to save space. Even when using an 802.11n wireless or Gigabit Ethernet connection, the initial backup of any Mac to the drive requires significant time; Apple suggests that the first backup will take "overnight or longer".[17] Subsequent backups are incremental, thus will typically be quicker, as they only include changed files. Clients using Mac OS X Snow Leopard, can perform the initial backup twice as fast as Leopard clients. The backup disk can also be used by Windows-based computers, and the files on it can be managed by another OS such as Windows.
