Acertant Technologies today released Versomatic 1.0 for Mac OS X, an extension to Apple's latest operating system that monitors and archives file changes automatically in the background. The entire process is completely transparent to users and is compatible with any application that saves files to disk. Versomatic can also recover deleted or accidentally over-written files, regardless of when they were deleted. The software is designed as part 'version control' and part 'incremental backup,' archiving changes in real-time as they happen. Users can right-click on a document to retrieve an earlier version of a document via a popup menu, which lists the file's entire revision history. Clicking on a date and time enables users to view or export a copy of the chosen revision, requiring no restore scripts or complicated queries. Versomatic supports all file types, is available for $40 through the month of November, and requires Mac OS X 10.4 or later.
