摘要： A method and system for migrating data and metadata from a first backup system to a second backup system via a staging system is disclosed. The system accesses the backup data from the first backup system and restores it, along with the associated metadata, to a staging system. A metadata file is created at the staging system which comprises of the metadata that is to be migrated to the second backup system. The system then migrates the data from the staging system to the second backup system. The metadata is also migrated to the second backup system in a format such that it can be indexed. As a result, the migrated data can be browsed and searched based on one or more search criteria based on the associated metadata. Other details are provided herein.

摘要： An information management system implements a method for securing a media agent from unauthorized access, where the method includes configuring a secondary storage computing device to initialize a filter driver at boot time and monitor process calls to a media agent, where the media agent provides read and write operations to a secondary storage device in communication with the secondary storage computing device. The filter driver may detect a process call to the media agent, and determine whether the process call is authorized. In response to a determination that the process call is authorized, the filter driver may allow the process call to request an operation be performed by the media agent, and the media agent may then perform the requested operation. If the filter driver determines that the process call is not authorized, the filter driver may ignore the process call for the requested operation.

摘要： An information management system supports the concurrent transfer of multiple extents from a client computing device having one or more files stored in a primary storage device. The client computing device determines whether one or more of the files are extent-eligible by comparing a file size of a file with a predetermine file size threshold. Based on the comparison, the client computing device determines that the file is extent-eligible, and determines a plurality of extents for the extent-eligible file. The client computing device may then concurrently transmit one or more of the extents of the extent-eligible file to one or more nodes in communication with the client computing device. The one or more nodes may index the received extents for later retrieval during a restore operation of the extent-eligible file. The one or more nodes may also validate the extents to ensure that the extents are not corrupted.

摘要： Systems and methods for performing file-level restore operations for block-level data volumes are described. In some embodiments, the systems and methods restore data from a block-level data volume contained in secondary storage by receiving a request to restore one or more files from the block-level data volume, mounting a virtual disk to the block-level data volume, accessing one or more mount paths established by the virtual disk between the data agent and the block-level data volume, and browsing data from one or more files within the block-level data volume via the established one or more mount paths provided by the virtual disk.

摘要： Certain embodiments described herein relate to an improved selective data backup system. In some embodiments, one or more components in an information management system can determine that a portion of the primary data scheduled for backup was previously backed up or is scheduled to be backed up as part of another backup operation. For example, a data agent performing a cluster-level backup operation for an entire cluster of storage servers may check whether any part of the primary data was previously backed up by a prior server-level backup operation for one of the storage servers in the cluster. If so, the data agent may skip, in the cluster-level backup operation, any portion of the primary data stored in the storage server previously backed up as part of the prior server-level backup operation.

摘要： An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage.

摘要： Embodiments disclosed herein include systems and processes for replicating one or more user computing systems of an information management system at an external resource system to create a backup or fallback of the user computing systems. Replicating the user computing systems may include replicating data as well as the applications, operating systems and configuration of the user computing systems. This replicated or fallback user computing system may be implemented on a virtual machine at the external resource system. Thus, if a user computing system becomes inaccessible, a new user computing system can be generated based on the backup copy of the user computing system at the external resource system. Further, in some embodiments, the copy of the user computing system may be interacted with at the external resource system. Thus, certain embodiments disclosed herein can be used to transition an information management system to an external resource system.

摘要： Virtual machine (VM) proliferation may be reduced through the use of Virtual Server Agents (VSAs) assigned to a group of VM hosts that may determine the availability of a VM to perform a task. Tasks may be assigned to existing VMs instead of creating a new VM to perform the task. Furthermore, a VSA coordinator may determine a grouping of VMs or VM hosts based on one or more factors associated with the VMs or the VM hosts, such as VM type or geographical location of the VM hosts. The VSA coordinator may also assign one or more VSAs to facilitate managing the group of VM hosts. In some embodiments, the VSA coordinators may facilitate load balancing of VSAs during operation, such as during a backup operation, a restore operation, or any other operation between a primary storage system and a secondary storage system.

摘要： Illustrative methods and systems for migrating a large amount of data from a source site to one or more cloud destination sites with minimal interruptions to the source site during the migration process. Configured media agents initiate specialized backup jobs on source data to create backup copies of a specified size that minimally impacts the source site. Those backup copies are received at storage management site and stored in cache. For each received data blob, the illustrative system restores the backup copies to the destination site in the format of the original application data.
