A method and system for enabling agentless backup and restore operations on a container orchestration platform. Specifically, the method and system disclosed herein may entail facilitating the implementation of backup (or restore) workloads in a containerized environment without the co-execution of secondary storage agents therein, which traditionally manage these backup (or restore) operations.

Data chunks sent to a content destination are tracked. It is determined whether content of a portion of an object to be sent to the content destination matches one of the data chunks previously sent to the content destination. In response to the determination that the portion of the object to be sent to the content destination matches one of the data chunks previously sent to the content destination, a source reference to the matching previously sent data chunk where the content destination can locally obtain the content for the portion of the object is provided to the content destination.

Techniques described herein relate to a method for managing jobs. Such techniques may include: generating a job completion entry that specifies that execution of a first job was completed within an estimated period of time for the first job, generating a second job completion entry that specifies that execution of a second job was not completed within a second estimated period of time for the second job, updating the job resource mapping model based on the first job completion entry and the second job completion entry to obtain a new updated job resource mapping model.

Methods, apparatuses, and systems for ensuring timely restoration of an application, including: determining, based on a plurality of factors, a projected time to complete an application recovery operation from a first execution environment to a second execution environment and generating a report based on the projected time to complete the application recovery operation.

Example implementations relate to virtual persistent volumes for containerized applications. In an example, a plurality of different storage mounts are acquired from a mix of storage types. A containerized storage virtualization system creates and manages a virtual persistent volume that aggregates the acquired storage mounts. A mount point of the virtual persistent volume is provided to the containerized application. The virtual persistent volume includes a hierarchical structure that relates data objects of the containerized application by content-based signatures to a root object.

Embodiments of the present disclosure provide a method, a device and a computer program product for storage management. The method comprises: obtaining time information related to a removal time point for a backup storage system, the time information indicating that a chunk in the backup storage system whose expiration time does not exceed the removal time point is to be removed; determining, from a removal period list, a target removal period whose end time does not exceed the removal time point, each removal period in the removal period list being mapped to at least one chunk element, the at least one chunk element representing at least one chunk in the backup storage system whose expiration time is within the removal period to which the at least one chunk element is mapped; determining at least one target chunk element to which the target removal period is mapped; and removing, from the backup storage system, at least one target chunk corresponding to the at least one target chunk element. Therefore, with this solution, expired chunks can be efficiently removed.

A virtual machine disk image file backup is selected among a plurality of virtual machine disk image file backups stored on a backup storage based on a backup update policy. A version of the selected virtual machine disk image file backup is mounted. Based on the backup update policy, an update to the mounted version of the selected virtual machine disk image file backup is applied without restoring the selected virtual machine disk image file backup. The updated version of the selected virtual machine disk image file backup is stored on the backup storage.

A uniform model for distinct types of data replication, including receiving, at a source data repository, an update to a dataset; generating, based on the update to the dataset, both metadata describing the update to the dataset and also a metadata representation of the dataset; and initiating, based on the same metadata describing the update to the dataset and also based on the same metadata representation of the dataset, either a first type of data replication or a second type of data replication from among a plurality of types of data replication.

Systems and methods for creating local, or on-premises, secondary copies of data managed and/or stored in online repositories are described. In some embodiments, the systems and methods perform a single application programming interface (API) call to a web application level of an online repository to transfer a copy of the data stored in the online repository from the online repository to a local site of a local information management system. Via the local site, the systems and methods access the copy of the data at the site of the local information management system, generate a metadata manifest file that associates metadata files and data files within the copy of the data of the site of the local information management system, and transfer the data files and the metadata manifest file to a media agent for storage to a secondary storage device of the local information management system.

According to the embodiments, an external storage device switches to an interface controller for supporting only a read operation of nonvolatile memory when a shift condition for shifting to a read only mode is met. A host device switches to an interface driver for supporting only the read operation of the nonvolatile memory when determining to recognize as read only memory based on information acquired from the external storage device.
