System and method for copy on write on an SSD

Techniques for improved copy on write functionality within an SSD are disclosed. In some embodiments, the techniques may be realized as a method for providing improved copy on write functionality within an SSD including providing, in memory of a device, an indirection data structure. The data structure may include a master entry for cloned data, the master entry having a reference to one or more indexes and a clone entry for the cloned data, the cloned entry having at least one of: a reference to a master index, a reference to a next index, and a value indicating an end of a data structure. The techniques may include traversing, using a computer processor, one or more copies of the cloned data using one or more of the references. 用于SSD上的写时复制的系统和方法。公开用于SSD中改进的写时复制功能的技术。在些实施例中，可将所述技术实现为用于在SSD中提供改进的写时复制功能的方法，包括在装置的存储器中提供间接数据结构。间接数据结构可包括用于克隆数据的主条目以及用于克隆数据的克隆条目，主条目具有对个或多个索引的引用，克隆条目具有以下至少个：对主索引的引用、对次索引的引用和指示数据结构结尾的值。所述技术可包括利用计算机处理器使用个或多个引用遍历克隆数据的个或多个副本。
