    摘要: Various embodiments are provided for facilitation of data retention using logical objects. Following an operation creating a redundant copy of the data performed on a scheduled interval, a logical object containing a number of managed file versions, represented by a number of member objects for a recovery point, is created. The logical object is assigned a policy of a data retention policy construct associated with the recovery point. The logical object is adapted for reassignment between policies of the data retention policy construct associated with various recovery points. During the reassignment, the plurality of member objects representing the plurality of managed file versions are logically retained instead of performing a data copy operation to associate the plurality of managed file versions with another recovery point.

    摘要: One aspect of the present invention includes a configuration of a storage management system that enables the performance of deduplication activities at both the client (source) and at the server (target) locations. The location of deduplication operations can then be optimized based on system conditions or predefined policies. In one embodiment, seamless switching of deduplication activities between the client and the server is enabled by utilizing uniform deduplication process algorithms and accessing the same deduplication index (containing information on the hashed data chunks). Additionally, any data transformations on the chunks are performed subsequent to identification of the data chunks. Accordingly, with use of this storage configuration, the storage system can find and utilize matching chunks generated with either client- or server-side deduplication.

    摘要: Provided are a computer program product, system, and method for encrypting data objects to back-up to a server. A client private key is intended to be maintained only by the client. A data object of chunks to store at the server is generated. A first portion of the chunks in the data object is encrypted with the client private key and the first portion of the chunks in the data object encrypted with the client private key are sent to the server to store. A second portion of the chunks in the data object not encrypted with the client private key are sent to the server to store.

    摘要: One aspect of the invention is a method for ensuring consistency of a group, which for example, includes receiving a first list that identifies objects in the group, and gathering for at least one attribute, the value of the attribute for each object in the first list. The first list, and the attribute values gathered in the gathering operation, are stored to create a first snapshot. This example also includes receiving a second list that identifies objects that are in the group after at least part of a task is performed, and the value after at least part of the task is performed of the at least one attribute for each object identified in the second list. The second list and the received attribute values are stored to create a second snapshot, which is compared with the first snapshot.
