    Abstract: In certain embodiments, a tiered storage system is disclosed that provides for failover protection during data backup operations. The system can provide for an index, or catalog, for identifying and enabling restoration of backup data located on a storage device. The system further maintains a set of transaction logs generated by media agent modules that identify metadata with respect to individual data chunks of a backup file on the storage device. A copy of the catalog and transaction logs can be stored at a location accessible by each of the media agent modules. In this manner, in case of a failure of one media agent module during backup, the transaction logs and existing catalog can be used by a second media agent module to resume the backup operation without requiring a restart of the backup process.

    Abstract: The automatic, tiered retention storage system according to certain aspects can automatically classify data items based on content, such as based on the inclusion of search terms in the data items, or based on metadata or other characteristics associated with the data. Based on the classification, the system can assign the data items to corresponding user-defined “buckets.” In some embodiments, each bucket is associated with a particular tier in the storage system having a specific retention period.

    Abstract: Described in detail herein is a method of copying data of one or more virtual machines being hosted by one or more non-virtual machines. The method includes receiving an indication that specifies how to perform a copy of data of one or more virtual machines hosted by one or more virtual machine hosts. The method may include determining whether the one or more virtual machines are managed by a virtual machine manager that manages or facilitates management of the virtual machines. If so, the virtual machine manager is dynamically queried to automatically determine the virtual machines that it manages or that it facilitates management of. If not, a virtual machine host is dynamically queried to automatically determine the virtual machines that it hosts. The data of each virtual machine is then copied according to the specifications of the received indication.

    Abstract: A storage manager that interoperates with a file manager application that integrates with virtualization substantially enables end-user control and storage management of virtual machines (VMs). The storage manager may manage information management operations relative to virtual machines based on and/or in response to messages and/or instructions received from the file manager application. The storage manager may further report results to the file manager application for presentation to the user. The file manager application, which may operate as a plug-in for a legacy file manager executing on a user's client computing device, may comprise: displaying the VMs associated with the user, including their respective properties; enabling viewing/browsing of information about storage management operations for a VM such as backups and/or archiving, including files associated with the VM and searching and filtering criteria; control features that enable the user to control existing VMs, such as shut down, restart/activate/power-on, suspend, and/or re-configure, and also perform storage management of a VM and/or its associated files, such as create snapshot, back up, archive, restore VM from secondary storage, restore and overwrite VM, restore file(s)/folder(s) to user's client computing device, restore file(s)/folder(s) to a production VM in primary storage, etc.; control features that enable the user to provision additional VMs, such as create a new VM, create a clone VM, configure a VM, etc.

    Abstract: A system for archiving data objects using secondary copies is disclosed. The system creates one or more secondary copies of primary copy data that contains multiple data objects. The system maintains a first data structure that tracks the data objects for which the system has created secondary copies and the locations of the secondary copies. To archive data objects in the primary copy data, the system identifies data objects to be archived, verifies that previously-created secondary copies of the identified data objects exist, and replaces the identified data objects with stubs. The system maintains a second data structure that both tracks the stubs and refers to the first data structure, thereby creating an association between the stubs and the locations of the secondary copies.
