    Abstract: A backup system includes a processor and a machine-readable storage storing instructions. The instructions are executable by the processor to: access a plurality of blocks included in a block-based backup of a first snapshot of a storage volume; determine, based on the plurality of blocks of the block-based backup, a first filesystem stored on the storage volume, the first filesystem being a first type of filesystem; select, from a plurality of filters, a first filter associated with the first type of filesystem; determine a changed file in the first filesystem based on the selected first filter; and update a catalog to indicate that the changed file is associated with the first snapshot.

    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: In one example an updated snapshot delta value is computed upon occurrence of a new transaction. The new transaction is a data modification operation performed on data blocks of the storage device. Further, the delta value indicates at least one of volume of data modified since creation of a reference snapshot and number of transactions performed since the creation. Subsequently, the updated snapshot delta value is compared with a corresponding threshold value. The threshold value is at least one of a predetermined volume of data modified and a predetermined number of transactions. A snapshot action is subsequently performed based on the comparison.

    Abstract: Examples described herein relate to management of containers in a storage system. Examples may receive a container specification corresponding to a container image. Examples may obtain the container image from a container repository and select storage volumes based on the container specification. Examples may execute one or more containers from the container image on a controller of the storage system within resource limits. Examples may dynamically select the controllers based on resource availability at the plurality of controllers. Examples may allow scheduling the execution of the containers at a specific controller at a predetermined time. The execution may include performing one or more batch operations on the storage volumes. Examples may further enable monitoring a status of the container and providing alerts in response to a detection of a failure event associated with the container.

    Abstract: In some examples, a local, non-tape based storage is to emulate tape storage elements at a first virtual tape library. A data structure associates first emulated tape storage elements of an emulated tape library with the storage elements in the first virtual tape library and associates second emulated tape storage elements of the emulated tape library with storage elements emulated by a remote storage in a second virtual tape library that is separate from the first virtual tape library, where the first virtual tape library is to present the emulated tape library that includes the storage elements of the first and second virtual tape libraries to a requesting entity that is separate from the first and second virtual tape libraries.
