A risk analysis of disk backup or repository maintenance
نویسندگان
چکیده
We discuss a simple model of disk backups and other maintenance processes that include change to computer data. We determine optimal strategies for scheduling such processes. A maximum entropy model of random change provides a simple and intuitive guide to the process of sector based disk change and leads to an easily computable optimum time for backup that is robust to changes in the model. We conclude with some theoretical considerations about strategies for organizing backup information..

Moving a repository of scholarly content to a cloud
Purpose – This paper aims to describe the problems faced by MyAIS, an open access repository of scholarly content, the reasons for moving to a cloud infrastructure and the design of the system. Design/methodology/approach – MyAIS is supported by an IBM HS22V multiple blade server using virtualization technology. A single blade server runs both MyAIS’s back-end that handles the processing of dig...
متن کاملA Framework for Building Unobtrusive Disk Maintenance Applications (CMU-CS-03-192)
This paper describes a programming framework for clean construction of disk maintenance applications. They can use it to expose the disk activity to be done, and then process completed requests as they are reported. The system ensures that these applications make steady forward progress without competing for disk access with a system’s primary applications. It opportunistically completes mainte...

متن کاملDesign and Implementation of a Storage Repository Using Commonality Factoring
In this paper, we discuss the design of a data normalization system that we term commonality factoring. A real-world implementation of a storage system based upon data normalization requires design of the data normalization itself, of the storage repository for the data, and of the protocols to be used between applications performing data normalization and the server software of the repository....
