Disk-based data replication, with its potential to speed the backup process and deliver instant data restore, is poised to revolutionize data protection. Gartner predicts that by 2008 the majority of data restores will occur from disk, not from tape. Disk is rapidly becoming a viable option for backup, but the question is how best to implement the new solutions? This paper examines the benefits of disk-based backup and compares three approaches: LAN-based backup, SAN-based backup, and the new SAN filer approach from ONStor. Exciting new alternatives are coming to market; read how these solutions differ and how they can enhance your backup and recovery processes.
