One embodiment is directed to a method for protecting data contained in a file of a computer system, wherein the computer system is useable to create multiple successive file versions. The method comprises the steps of specifying a maximum number of file versions that can be stored collectively at first and second storage locations, and apportioning the maximum number into a first number of file versions and a second number of file versions. The method further comprises storing the most recent of the multiple file versions, up to a number equal to the first number, at the first storage location. A number of file versions respectively created before the stored most recent versions, up to a number equal to the second number, are stored at the second storage location, over a pre-specified time period and in accordance with a pre-specified strategy.
