Research on the media Forensics service system based on cloud model Hui Wenlin Shohaiying According to the problems faced by the existing media forensics system, combined with the idea of cloud computing, this paper proposes a media forensics service system based on cloud mode. In view of the heterogeneity of large-scale media forensics service, several challenges, such as scalability and efficiency, this paper creatively proposes a three-layer media forensics service architecture model by using the hierarchical structure model, and expounds the key technologies involved in this model, namely resource virtualization, System task parallelism and adaptive ability, and finally gives ...

With the rapid growth of the amount of storage data, more and more people begin to pay attention to the method of reducing storage data. Data compression, single-instance storage, and duplicate data deletion are frequently used storage data reduction techniques. Duplicate data deletion often refers to the elimination of redundant child files. Unlike compression, duplicate data deletion does not change the data itself, but eliminates the storage capacity that the same data occupies. Data de-duplication has a significant advantage in reducing storage and reducing network bandwidth, and is useful for scalability. As a simple example: in the special for telecommunications operations agreed to the call details to apply ...

Today's content is very simple and very real, and at some point we need to take snapshots of our virtual machines, which have been renamed checkpoints in server R2, but the functionality is still exactly the same. Today, we are not going to discuss the deep workings of the snapshot feature, but rather how to make it easier to do snapshot operations. Perhaps a lot of friends are asking, the snapshot is not the right button, the snapshot? To do so, we can select the virtual machine to take snapshots, and then right-click to select the snapshot. In addition to a single virtual machine to take snapshots, we can also select multiple virtual machines, using ...
