Abstract: Method and system for performing recovery for a replicated copy of a storage space presented as a logical object is provided. An attribute associated with the logical object for enabling the recovery is set and when the storage space is replicated the attribute is stored as metadata for the replicated copy of the storage space. Based on the attribute, a clone of the logical object is presented as a writable option to write to the first replicated copy. After the write operation where information is written to the clone, a second replicated copy with the clone information is created. The clone is deleted after the second copy is generated.

Abstract translation: 提供了用于为呈现为逻辑对象的存储空间的复制副本执行恢复的方法和系统。 设置与用于启用恢复的逻辑对象相关联的属性，并且当存储空间被复制时，该属性被存储为存储空间的复制副本的元数据。 基于该属性，逻辑对象的克隆被呈现为写入第一个复制副本的可写选项。 在向克隆写入信息的写入操作之后，创建具有克隆信息的第二个复制副本。 生成第二个副本后，克隆被删除。
