Abstract: The illustrative systems and methods advantageously reduce the amount of storage space occupied by data that no longer has a useful life—as established by the data objects' user(s) and overcoming predetermined rules required by information management policies. An illustrative data agent may receive instructions from an illustrative storage manager to perform secondary copy operations for a given set of data objects. The instructions may generally instruct that expiry-marked data objects are to be treated based on parsing each data object's user-supplied expiry timeframe. The illustrative system (i) will delete expired data objects including expired secondary copies; (ii) will refrain from making secondary copies of expired data objects; and (iii) if an expiry-marked data object is not expired, the illustrative system will make secondary copies according to the instructions from the storage manager, but will track those expiry-marked secondary copies for future deletion after they expire, (iv) and will delete expired secondary copies even if the original expiry-marked data object has been deleted from the system prior to its expiration.

Abstract: An illustrative storage management appliance is interposed between client computing devices and one or more cloud storage resources. The appliance uses cloud storage resources in conjunction with a network attached storage device configured within the appliance to provide to the client computing devices seemingly unlimited network attached storage on respective network shares. The storage management appliance monitors data objects on the network shares and when a data object meets one or more criteria for archiving, the storage management appliance archives the data object to a cloud storage resource and replaces it with a stub and preview image on the network share. When access to the stub and/or preview image is detected, the storage management appliance restores the data object from the cloud storage resource. The criteria for archiving flexibly allow individual data objects to be archived to cloud storage without archiving frequently-accessed “neighboring” data objects on the same network share.

Abstract: 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.

Abstract: Systems and methods are disclosed for block-level incremental replication of a local file system in a source volume/partition to a storage array—replicated to a single logical disk designated by a logical unit number (LUN) with a single volume/partition corresponding to the source. From the perspective of the storage array, non-native data (e.g., data in a local file system residing in locally-attached storage) may be backed up to a LUN that is native to the storage array and thus available for any number of subsequent LUN-based operations. Enhanced data agents, media agents, and storage manager(s), including replication storage policies, operate in concert with the storage array to execute successive file-system-to-LUN block-level replication jobs to protect the data in the local file system.

Abstract: Snapshot-based disaster recovery (DR) orchestration systems and methods for virtual machine (VM) failover and failback do not require that VMs or their corresponding datastores be actively operating at the DR site before a DR orchestration job is initiated, i.e., before failover. An illustrative data storage management system deploys proprietary components at source data center(s) and at DR site(s). The proprietary components (e.g., storage manager, data agents, media agents, backup nodes, etc.) interoperate with each other and with the source and DR components to ensure that VMs will successfully failover and/or failback. DR orchestration jobs are suitable for testing VM failover scenarios (“clone testing”), for conducting planned VM failovers, and for unplanned VM failovers. DR orchestration jobs also handle failback and integration of DR-generated data into the failback site, including restoring VMs that never failed over to fully re-populate the source/failback site.
