Abstract:
A system and method for repairing potentially corrupt file systems are provided. A request to repair an original file system, including a current set of metadata, is received. A metasave image is accessed, in response to the request. The metasave image includes a copy of the metadata included in the original file system at a point-in-time and information identifying a location of each block of metadata in the metasave image. Using the metasave image information, the current set of metadata in the original file system is replaced with the metadata in the metasave image.
