    摘要： Performing a backup is disclosed. A changed portion of a file system tree is determined based at least in part on a stored state of the file system tree at a time a prior block based backup of the file system tree was performed. Incremental metadata associated with the changed portion is obtained. The obtained incremental metadata is stored where there is at least some metadata associated with an unchanged portion of the file system tree that is not stored when storing the obtained incremental metadata.

    摘要： Identifying a file system element for restoration is disclosed. The technique comprises of receiving a request to restore a file system element; determining an offset indicating where a record associated with the file system element is located within a collection of records, wherein the record includes metadata related to stored data to be used to restore the file system element; and using the determined offset to retrieve the record from the collection of records.

    摘要： Memory is used, including by receiving at a processor an indication that a first piece of metadata associated with a set of backup data is required during a block based backup and/or restore. The processor is used to retrieve from a metadata store a set of metadata that includes the first piece of metadata and one or more additional pieces of metadata included in the metadata store in an adjacent location that is adjacent to a first location in which the first piece of metadata is stored in the metadata store, without first determining whether the one or more additional pieces of metadata are currently required. The retrieved set of metadata is stored in a cache.
