摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method and system for detecting ransomware and repairing data following an attack. The method includes, collecting file statistics for files in a file system, identifying an affected file based on collected file statistics, locking down of access to the file system in response to identifying the affected file, undoing of reconcile processing, repairing the affected files, and unlocking access to the file system. The system includes a computer node, a file system, a plurality of disc storage components, a backup client, a backup client, and a hierarchical storage client. The hierarchical storage client is configured to collect file statistics for files in file system, identify affected files based on collected file statistics for the file, lock down of access to the file system in response to an identified affected file, undo reconcile processing, repair the affected file; and unlock access to the file system.

摘要： Provided are techniques for providing and managing data protection by using incremental forever for storage to cloud object stores. An incremental offload is performed by using one or more extents to identify blocks of data for a version of a virtual machine in operational recovery storage to be offloaded to a cloud object store, wherein each of the one or more extents identifies locations of the blocks of data. The blocks of data are converted to objects in an incremental forever data format. The objects are offloaded to the cloud object store. The details of the offloading of the objects are stored in a local database in the operational recovery storage. The local database is copied from the operational recovery storage to the cloud object store as a database copy.

摘要： A method for executing complex data protection operations is disclosed. In one embodiment, such a method includes generating multiple complex data protection operations, where each complex data protection operation includes multiple data protection functions pre-arranged in a specified order and on a specified schedule. The method further presents the multiple complex data protection operations to a user in the form of a menu. This menu includes multiple menu options, where each menu option is associated with one of the complex data protection operations. The method further enables the user to select a menu option, and executes the complex data protection operation associated with the menu option selected by the user. A corresponding system and computer program product are also disclosed.

摘要： A backup system retains a certain number of file versions in backups of a virtual machine running on a host computing system. Files are identified that have changed on the virtual machine since storing a backup of the virtual machine on a backup server. Host blocks on that are associated with each of the changed files are determined. Backup blocks associated with each of the host blocks are determined. The changed files and associated backup blocks are merged with previous file version information. It is determined that a version of a file has become expired, the version of the file associated with a backup block. The backup block is deleted in response to determining that the backup block is not associated with any unexpired file versions and the backup block is not associated with any unexpired virtual machine backups.
