Access "Snapshots: The alternative backup"
This article is part of the Vol. 9 Num. 9 January 2011 issue of Exploring near-continuous data protection for operational recovery
How do you beat the backup window? Use snapshots and you can forget about backup windows. Snapshot-based backup, also known as near-continuous data protection (or near-CDP), currently offers one of the most cost-effective, worry-free and efficient ways to provide operational recovery. Before we get into why, let's first look at a few of the alternatives. Tape systems, when used in conjunction with a traditional data backup system, are the most cost-efficient way to provide long-term storage of backups and archives; however, the mismatch between the speed of backups and the speed of modern tape drives creates quite a challenge when performing operational backup and recovery directly to and from tape. A popular option is to augment tape with a data deduplication target for your traditional backup system. This significantly improves the efficiency of traditional backup systems and reduces the amount of ongoing maintenance they need; however, dedupe systems aren't cheap. And while deduplication technology makes backups more efficient, it does so using a very ... Access >>>
