Optimization of Backup Storage by Reducing Fragmentation in Distributed Environment
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
In modern backup systems, Deduplication plays a vital role in the elimination of duplicate data in a storage system which one of the technique to reduce storage costs. Deduplication divides a backup stream into variable sized chunks of data used to map stored chunks to their physical addresses. These chunks of data are physically distributed and create a problem known as fragmentation. Primarily fragmentation categorized into sparse and out-of-order containers. The sparse container adversely affects the performance while restoring the database and garbage collection effectively, while the out-of-order container brings an adverse effect on the performance issue if the restore cache built is small. To minimize the fragmentation problem, we implement the History-Aware Rewriting algorithm (HAR) and Cache-Aware Filter (CAF). HAR will collect the historical information in backup systems to identify and reduce sparse containers, and CAF to restore cache knowledge to find the out-of-order containers that impacts restore performance. We exploit Container-Marker Algorithm (CMA) to gather valid containers instead of valid chunks which help in garbage collection. My results help to prove how HAR, CMA improves the restore performance.
