Managing snapshots stored locally in a storage system and in cloud storage utilizing policy-based snapshot lineages

An apparatus includes a processing device configured to identify a snapshot policy for creating a snapshot lineage comprising snapshots of a storage volume comprising data stored on a storage system, the snapshot lineage comprising (i) a local snapshot lineage stored on the storage system and (ii) at least one cloud snapshot lineage stored on cloud storage. The processing device is also configured to generate snapshots of the storage volume in accordance with the snapshot policy, to store the snapshots in the local snapshot lineage, and to copy snapshots from the local snapshot lineage to the at least one cloud snapshot lineage in accordance with the at least one snapshot policy. The processing device is further configured to provide an interface for managing the snapshot lineage by accessing, from the storage system, snapshots of the storage volume in the local snapshot lineage and the at least one cloud snapshot lineage.

BATCH DELETION METHOD AND APPARATUS FOR CACHE CONTENTS, DEVICE AND READABLE STORAGE MEDIUM
20220405244 · 2022-12-22 ·

A batch deletion method, apparatus, and device for cached content and a non-transitory computer-readable storage medium are disclosed. The method may include: adding keywords to content identifiers which correspond to cached resources (S101); saving the content identifiers separately (S102); finding, through a keyword-based query, content identifiers meeting at least one condition (S103); locating storage paths of cached resources by using the content identifiers meeting the at least one condition (S104); and deleting the located cached resources one by one (S105).

METHOD FOR PROCESSING A SYSTEM IMAGE
20220405242 · 2022-12-22 ·

A method for processing a system image, which represents an image of a file system. Each file in the file system is assigned an attribute, this attribute representing a last access time to this file, Initially the attributes of all files are set to a predefined value. The system image is executed, and then all attributes being checked. Finally the files are deleted whose attribute has the preset value.

Management system and control method

A management system gives an instruction to assign a value of an attribute corresponding to an environment where a processing system including a virtual machine started using a system image file is constructed, to the system image file, determines, based on a condition according to the value of the attribute assigned to the system image file in response to the instruction, whether the system image file is to be deleted, and gives an instruction to delete, from a storage device, the system image file that has been determined to be deleted.

Time-based virtual machine reversion

Recovery points can be used for replicating a virtual machine and reverting the virtual machine to a different state. A filter driver can monitor and capture input/output commands between a virtual machine and a virtual machine disk. The captured input/output commands can be used to create a recovery point. The recovery point can be associated with a bitmap that may be used to identify data blocks that have been modified between two versions of the virtual machine. Using this bitmap, a virtual machine may be reverted or restored to a different state by replacing modified data blocks and without replacing the entire virtual machine disk.

Temporary reservations in non-relational datastores

Systems, methods, and computer-readable media for temporary reservation schemes, are provided. In embodiments, temporary reservations are inserted into non-relational datastore, and update records indicating changes to the non-relational datastore are streamed to processing nodes. The processing nodes store the update records in local expiration windows. The expiration windows are periodically polled for expired temporary reservations, which are then removed from the non-relational datastore. Other embodiments may be described and/or claimed.

Efficiently deleting data from objects in a multi-tenant database system

Systems, apparatus, methods and computer program products for deleting data of an object within a multi-tenant database via an efficient delete operation are described herein. The new delete operation (or method) may be configured to identify one or more records to be deleted within a data structure such as an object. In order to ensure that the operation is efficient, the mechanism may determine characteristics of a data store and determine whether the information provided within the data structure provides an efficient identification of the data to be deleted. Upon a successful validation, an initial delete request may be translated to an appropriate delete operation for the underlying database.

Systems and tools for data archiving

Systems and methods to select an object instance from a database storage to archive to an external storage based on an archiving configuration and attribute values of the object instance, transmit the selection to an application associated with the object instance, determine, based on a response received from the application, to archive the object instance, mark the object instance as ready for archiving, identify the object instance as ready for archiving, convert the object instance to an object notation format, transmit the converted object instance to a cloud application for storage in an external storage, in response to a determination that the storage in the external storage is successful, create an index object in the database storage including a subset of fields of the object instance and a link to the converted object instance stored in the external storage, and mark the object instance in the database storage as archived.

MANAGEMENT OF ERASURE OR RETENTION OF USER DATA STORED IN DATA STORES

Techniques for managing erasure of data are presented. In response to receiving a request for erasure of data from a set of data stores, an erasure component can analyze a set of rules and information relating to the user account, including an account status and erasure hold status associated with the user account. The set of rules can be based on legal or contractual obligations applicable to the set of data stores, and can indicate various conditions under which data associated with a user account of a user can be eligible to be erased from the set of data stores or an associated data vault repository. The erasure component can determine eligibility for erasure of all or a portion of the set of data from the set of data stores based on the analysis results. Erasure component can determine erasure eligibility scores to pre-qualify user accounts for erasure eligibility.

Streams on shared database objects

A database platform can track changes using a stream that records changes made by database transactions. Streams on views can be implemented by applying a stream to source data, and applying the view to the streamed data. Users of the database platform can query the stream on the view to review recent changes to the view, such as changes made since the last database transaction.
