Cloud Backup Scheduling Algorithm Based on Cloud State Table and Cloud Resources Table

As an application of cloud storage, cloud backup is effective, reliable, extensible, cost-effective and usable, which makes cloud backup having a broad prospect of application. We proposed a reliable cloud backup scheduling algorithm that showing good performance. In this algorithm, data access time and data reliability are introduced. With the cloud state table and cloud resources table, the algorithm determines which cloud storage node will save the data. The simulated experiment shows that the proposed algorithm, guaranteeing the data reliability, gets good data access performance.
