摘要： Provided are techniques for exploiting object tags in order to produce a work order across several backup engines for a backup job. A selection of tags for an object is received. A work order for the object is created using the tags. The work order is stored with a virtual server that stores the object, wherein a data mover of a backup engine retrieves the work order from the virtual server to back up the object.

摘要： For accessing files from block-level backups of a virtual disk, an apparatus is disclosed. The apparatus includes a changed block module that obtains a list of changed blocks between a previous and a current backup of a virtual disk. The apparatus includes a mapping module that maps logical clusters of the virtual disk to the changed blocks and identifies files corresponding to the logical clusters. The apparatus further includes a changed file module that designates the files corresponding to the logical clusters as changed files, unless current attributes of the files for the current backup match attributes of the files in a backup file index corresponding to the previous backup of the virtual disk. The changed file module further stores the current attributes and extents for the changed files within blocks of a backup storage device for updating in the backup file index.

摘要： A mechanism is provided for caching backed-up data locally until successful replication of the backed-up data. Responsive to an indication to back up one or more pieces of identified data from a local storage device, a determination is made as to whether a primary storage device is available. Responsive to the primary storage device being available, the one or more pieces of identified data are backed up to the primary storage device and a local replication cache. Responsive to the backed-up data being replicated from the primary storage device to a secondary storage device, the backed-up data is removed from the local replication cache.

摘要： Provided are a computer program product, system, and method for hypervisor agnostic interchangeable backup recovery and file level recovery from virtual disks. Data is stored for a first virtual disk that represents data in a first format and metadata for the first virtual disk in a common data format in a storage having a fixed block length. A virtual disk file represents data in a second format that allows variable size blocks. Multiple instances of the fixed block length of blocks of data for the second virtual disk indicated in the virtual disk file are read. Each instance of the read fixed block length of blocks is written to the storage in the common data format with metadata describing the format of the blocks in the second virtual disk, and can be restored to a third virtual disk in the first or second format.

摘要： A system correlates application information from within a virtual guest to an entity managing off-host data protection. During a data protection operation, the system exploits the virtual hierarchy to centralize the configuration and management of operating system credentials of numerous virtual guests. For each virtual guest, the system uses the credential to collect a single Globally Unique Identifier (GUID) previously generated and stored in-guest by any data protection agent. The system stores the collected GUID as a custom property in the context of the virtual hierarchy. The system also exploits the virtual hierarchy custom properties to determine if GUIDs are copies due to virtual guest replication. The system ensures GUID's uniqueness by requesting regeneration of the GUID by in-guest data protection agents. Using GUIDs that are unique across the virtual hierarchy, from the entity managing off-host data protection, the system can correlate application data of multiple in-guest data protection agents.
摘要翻译：系统将来自虚拟客户端的应用信息与管理脱离主机数据保护的实体相关联。在数据保护操作期间，系统利用虚拟层次结构来集中许多虚拟客户端的操作系统凭据的配置和管理。对于每个虚拟客户端，系统使用凭据来收集任何数据保护代理先前生成和存储在客户机中的单个全局唯一标识符（GUID）。系统将收集的GUID作为自定义属性存储在虚拟层次结构的上下文中。系统还利用虚拟层次结构自定义属性来确定GUID是否是由于虚拟客户机复制而导致的副本。系统通过请求由访客数据保护代理重新生成GUID来确保GUID的唯一性。使用在虚拟层次结构中唯一的GUID，来自管理脱离主机数据保护的实体，系统可以将多个来访者数据保护代理的应用程序数据相关联。

摘要： The present invention optimizes the utilization of computer system resources by considering predefined performance targets of multithreaded applications using the resources. The performance and utilization information for a set of multithreaded applications is provided. Using the performance and utilization information, the invention determines overutilized resources. Using the performance information, the invention also identifies threads and corresponding applications using an overutilized resource. The priority of the identified threads using said overutilized resource is adjusted to maximise a number of applications meeting their performance targets. The adjustments of priorities are executed via a channel that provides the performance and utilization information.

摘要： For restoring deduplicated data, a method maintains a chunk index on a client computing system coupled to a client data store. The chunk index tracks chunks within files remaining on the client data store after storage of the files to a deduplicated server data store coupled to a server computing system. The method determines whether a valid entry for a first chunk exists in the chunk index. In addition, the method retrieves the first chunk from the server data store responsive to determining the valid entry for the first chunk does not exist in the chunk index. The method further retrieves the first chunk from the client data store specified in the valid entry of the chunk index responsive to determining that the valid entry exists in the chunk index and the first chunk resides in a first file at a first offset.
