The cloud storage is a new paradigm of data storage. Because of the internet connection speed increasing, everyone can store data on the cloud storage. Some data is shared for many user accesses, some data is private data. It has different characteristic of access pattern. In this work, the adaptive dynamic replication is presented. The model of dynamic replication is discussed. We propose the object-based storage as our cloud storage architecture. The storage object life time is used for handle our dynamic replication mechanism. The experimental results show the distribution of storage object workload that has some characteristic that relate with storage object life time and other factors.
