NTI Shadow backup for OS X
this week debuted NTI Shadow, a convenient, always-on, data backup solution for PC and Mac users. "With NTI Shadow, users can set the program to automatically back up their important files in native format every time a change occurs. The backup data is always in sync with the original." The application operates transparently in the backgroun and includes a step-by-step wizard to simplify setup and scheduling, allowing users to maintain real-time, continuous backup of all changed files or just specific file types. Users can also archive multiple revisions of important files. NTI Shadow can also be used to synchronize digital content stored on USB pen drives or USB MP3 players.
