| Abstract | A consistent backup, preserving data integrity across files in a file system, is of utmost importance for the purpose of correctness and minimizing system downtime during the process of data recovery. With the present day demand for continuous access to data, backup has to be taken of an active file system, putting the consistency of the backup copy at risk. We propose a scheme to take a consistent backup of an active file system assuming that the file system supports transactions. We take into consideration that file operations include, besides reading and writing of files, directory operations, file descriptor operations and operations such as append, truncate, etc. We are putting our scheme into a formal framework to prove its correctness and we have devised algorithms for implementing the scheme. We intend to simulate the algorithms and run experiments to help tune the algorithms. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
