Abstract
An improved system and method for using a file system to automatically backup a file in persistent storage is provided. A storage aggregator may organize nonvolatile memory for use in aggregate to store backup copies of a file. A file system filter driver may receive a request from an application for storing a file and may access a policy to determining whether to create a backup copy of the file and what type of backup to apply to the file. A generational file handler may create and manage a set of generational files as backup copies of a particular application file. And a recovery user interface may be provided to retrieve one or more backup copies, such as the set of generational files, for inspection by a user to recover whatever copy of the file may be desired by the user.
