Abstract: A method for backing a computing system includes generating a local history table of filesystem objects that have changed since storing a first backup of the computing system where the local history table includes attributes of the filesystem objects and a set of operations associated with changes to the filesystem objects. The method further includes transferring, from the computing system to a backup server, a second backup of the computing system, where the second backup includes a block level representation of a portion of a data storage medium associated with the computing system. The method additionally includes merging the local history table with a global history table stored on the backup server, the global history table mapping a history of filesystem objects to a set of block level backups of the computing system including the first backup of the computing system and the second backup of the computing system.

Abstract: A method for accessing filesystem objects on a backup server storing block level backups, includes: receiving a request to access a filesystem object stored in the block level backups, the request including a pattern of characters identifying the filesystem object in a global history table mapping a history of filesystem objects to the block level backups; identifying, based on the pattern of characters, an object identifier in the global history table corresponding to the filesystem object; identifying, based on the object identifier, a set of one or more block level backups of the computing system having a copy of the filesystem object; selecting a block level backup from the set of one or more block level backups; mounting the selected block level backup to access a backed-up file system of the computing system; and retrieving, from the backed-up filesystem, the filesystem object.

Abstract: In an approach to backup and restore one or more clone file trees, one or more processors generate a clone management table. One or more processors record a clone management information in the clone management table about each clone file. To backup a clone file, one or more processors update the clone management information, and store one or more data blocks that are in the clone file trees. To restore a clone file, one or more processors analyze a clone management information and restore one or more data blocks in the clone file. To restore a clone file parent, one or more processors analyze a clone management information and restore one or more data blocks in the clone file parent. To restore a clone file tree, one or more processors analyze a clone management information and restore one or more data blocks in the clone file tree.

Abstract: Embodiments for managing data in a hierarchical storage server storing data blocks of a database system comprising primary storage devices being in an active mode and secondary storage devices being in one of an active and passive mode are provided. In response to read and write requests for data blocks at logical storage locations, a block mapping device determines physical storage locations on the storage devices. Read requests switch over secondary storage devices to the active mode when they are in the passive mode. Write requests write data blocks only to the primary storage devices. Secondary storage devices that have not been accessed for a minimum activation time may be switched over from the active to the passive mode to save power consumption and cooling. Data migration and data recall policies control moving of data blocks between the primary and secondary storage devices and are primarily based on threshold values.
