| Article Name : | | | A SURVEY OF BACKUP RECOVERY SYSTEM FOR INSTANT RESTORATION OF DATA SERVICES | | Author Name : | | | Nitin D. Magdum and Manik A Raichurakar | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-6599 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | W e propose Birds: a bare-metal recovery system for instant restoration of data services, focusing on a general-purpose automatic backup-and-recovery approach to protect data and resume data services from scratch instantly after disasters. We design BIRDS to possess two appealing features: full automation in the backup-and-recovery process, and instant data service resum- ption after disasters. BIRDS achieves the former one with auto- matic whole system replication and resto- ration, by tak ing the backup process- outside of the prote- cted system with the help of a novel non-intrusive light-weight physical to virtual conversion method. The latter oneis enabled by a novel pipelined parallel recovery mechanism, which allows data services being instantly resumed while data recoverybetween the backup data center and the production site is still in progress. We implemented a BIRDS prototype and evaluated it usingstandard benchmarks. We show that BIRDS outperforms existing disaster recovery techniques by the means of recovery efficiencywhile introducing relatively small runtime overhead. Furthermore, BIRDS can be directly applied to any existing system in a plug-and-protect fashion without requiring re-installation or any modification of the existing system. | | Keywords : | | - Backup/recovery, rel-i ab- ility, ava- ilability,se-r viceability,
