Simple Backup Utility
is the solution for enterprise clients who are unable to utilize Apple's Time Machine
because of its limitations in routed environments. While there are many known "hacks" that allow Time Machine to function in unintended scenarios, the results are often unreliable.
Simple Backup Utility is highly reliable and extremely unobtrusive. It lives in the menu bar and displays its status with colored icons and tool-tip notices that are only visible when you hover the cursor over its icon.
