摘要

本文解决了存储在远程存储设施中的数据的恢复问题，其中用户数据分布在具有相同数量存储单元的存储节点中。解决的问题是在通常发生的情况下获得不间断的数据可用性，其中对整个数据存储节点的访问丢失是暂时的，或者涉及位于不同节点的两个数据存储单元。解释了备份过程，并详细说明了计算必要校验和所需的计算。给出了各种情况下数据恢复计算的理论一般形式。通过一个算例对该方案进行了说明。

A Method for Cloud Storage Data Recovery with Limited Loss of Access

In this paper, the problem of recovering data stored in remote storage facilities is addressed, where user data are distributed in storage nodes, each possessing the same number of storage units. The problem addressed is getting uninterrupted data availability in the commonly occurring case where loss of access is temporary towards an entire data storage node, or concerns up to two data storage units located at different nodes. The backup procedure is explained and details are given about the calculations necessary for calculating the necessary checksums. The theoretical general form of the calculation of the data recovery in all instances is given. The scheme is illustrated via an arithmetic example.
