    摘要: This disclosure is describes a system and method for organizing and storing backup data by inode number. Data objects on a file system may be streamed to a backup client that identifies the inode numbers for each streamed data object before streaming the objects to storage. The inode numbers are parsed to create one or more inode directories that can be browsed during a recovery process. In this fashion, the file system can be quickly backed up without requiring the backup client to determine the file system's directory hierarchy.

    摘要: Views of files in an archival data storage system are generated by a backup view generator. A storage application generates and stores archival data in an archive system, the archival data corresponding to client data stored on a server or in memory associated with one or more client nodes. The storage application also generates backup files of the archival data which may be stored in a local memory. A set of metadata attributes are associated with each of the backup files. The backup views are generated by comparing metadata values in a view definition file to the sets of attributes associated with the backup files. Generated backup views can be exported for processing, including searching the backup views or displaying the backup views in a user interface.

    摘要: A priority restore agent in a data storage system generates a priority restore data set for a client computer system or device by identifying a set of active data sets and/or a set of key data sets within client system data generated by the client computer system. The priority restore agent looks at or processes file system attributes for the client system data and compares these attributes with predefined restore parameters. The restore parameters may indicate that any file that has been accessed, modified, or created within a particular period of time be included in the priority restore data set. The key data sets may be identified in a set of automated restore rules. A data protection application within the data storage system can restore data in the priority restore data set onto the client computer system after a disaster or system crash.

    摘要: New full backups are generated by combining an incremental backup with a previous full backup. A previous full backup is stored in a backup server in a hash file system format. A file server generates an incremental backup of a data set on the file server by identifying and dumping files/directories of the data set that are new/modified into a tar file that is sent to an accelerator. The accelerator parses the incremental backup tar file and converts it to a hash file system format that includes metadata, hash values, and new/modified data atomics. The accelerator merges the incremental backup into the previous full backup to generate a new full backup by altering metadata and hash values of a copy of the previous full backup such that the resulting metadata and hash values describe and point to new/modified directories and files as well as unmodified directories and files.

    摘要: Techniques for deduplicating a backup stream with ACL data embedded therein are described. According to one embodiment, a storage system receives a backup stream from a client, where the backup stream includes multiple data streams to be stored in the storage system. Each data stream represents a file or a directory of one or more files of a file system associated with the client. The storage system is to scan the backup stream to recognize an access control list (ACL) marker associated with at least one of the data streams, where the ACL marker identifies ACL data representing an ACL of the at least one data stream. The storage system is to chunk using a predetermined chunking algorithm the ACL data into a plurality of ACL data chunks to be stored in the storage system in a deduplicated manner.
