使用逻辑对象的数据保留

Data retention using logical objects
Abstract:
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.
