Abstract: Example implementations relate to backup operations in a storage system. An example includes a medium storing instructions to: detect a trigger event to initiate a backup restoration of a data entity at a local storage system; determine a user preference between a speed priority and a cost priority; based at least on the determined user preference, select between: an indirect restoration option in which a first portion of the backup data stored on the remote storage system is combined with a second portion of backup data stored on a gateway device to restore the data entity at the local storage system; and a direct restoration option in which the backup data stored on the remote storage system is restored at the local storage system without being combined with other backup data; and restore, using the selected first restoration option, the data entity at the local storage system.

Abstract: Examples described herein relate to a data protection policy management system (DPPMS) for tuning a data protection policy in events of failures. The DPPMS may detect a failure associated with an application that is protected via the data protection policy that includes settings corresponding to parameters comprising one or more of copy tiers, a data retention interval and a recovery point objective (RPO) for the copy tiers. The DPPMS may determine a type of the failure associated with the application. Further, the DPPMS may select, based on the type of the failure, at least one parameter of the parameters to be tuned in response to detection of the failure. Moreover, the DPPMS may tune the settings corresponding to the at least one selected parameter to adapt the data protection policy.

Abstract: Examples include migration of an application from a first storage system to a second storage system. Some examples identify a set of reference datablocks related to an application to be migrated, copy the set of reference datablocks and compute a snapshot delta value. When the snapshot delta value is less than the threshold value, the application is transitioned from the first storage system to the second storage system.

Abstract: Example implementations relate to determining a storage utilization attributable to object data stored in deduplicated form. The storage utilization attributable to the object data may be determined from an amount of object data not shared with other objects of the deduplication store and a portion of an amount of object data shared with other objects of the deduplication store. It is determined whether the storage utilization results in exceeding a storage threshold of a storage tier to which the object data is assigned. Where the storage utilization is determined to exceed the storage threshold, the object data may be reassigned to a different storage tier, or data of another object may be removed from the storage tier.

Abstract: Methods to provide workload performance control are described herein. Performance statistics for a plurality of workloads are obtained for a second time interval, which includes a plurality of first time intervals. The performance statistics is based on monitored data (220) obtained at each of the plurality of first time intervals. From the plurality of workloads, at least one workload having an anomaly in resource allocation is identified using the performance statistics. Resources, to at least mitigate the anomaly are associated with the at least one workload.
