  • Recovering files in data storage systems
    Patent number: 8612382
    Abstract: A method is used in recovering files in data storage systems. A set of file system blocks of a file of a file system is identified. The set of file system blocks are associated with a portion of an inode of the file of the file system. Mapping information associated with the portion of the inode is missing references to the set of file system blocks. Metadata of each file system block of the set of file system blocks is evaluated. Based on the evaluation, the portion of the inode of the file is recovered by updating mapping information associated with the portion of the inode.
