Abstract: A method begins with storage units receiving a request to transfer a copy of a set of encoded data slices from two or more source virtual storage vaults to a destination virtual storage vault. The method continues with each storage unit obtaining a slice transfer map and determining whether the storage unit supports one of the two or more source virtual storage vaults. For each supporting storage unit, the method continues with each supporting storage unit determining, based on the slice transfer map, a sub-set of encoded data slices of the set of encoded data slices that is stored within the one of the two or more source virtual storage vaults by the supporting storage unit. The method continues with the supporting storage unit sending the sub-set of encoded data slices to a corresponding storage unit that is supporting the destination virtual storage vault.

Abstract translation: 方法开始于存储单元接收将一组编码数据片段的副本从两个或更多个源虚拟存储库转移到目的地虚拟存储库的请求。 该方法继续每个存储单元获得切片传送图并确定存储单元是否支持两个或更多个源虚拟存储库中的一个。 对于每个支持存储单元，该方法继续，每个支持存储单元基于切片传输图确定存储在两个或更多个源中的一个中的编码数据片段集合的编码数据片段的子集 虚拟存储库由支持存储单元。 该方法继续支持存储单元将编码数据片段的子集发送到支持目的地虚拟存储库的相应存储单元。
