Data replication is great for protecting critical data and ensuring quick recoveries. Find out where you should deploy replication: in your array, network or servers. Data replication as a means of data protection has seen continuous and increasing adoption since it first emerged in storage systems after the first World Trade Center bombing in 1993. Over time, it has evolved into an indispensable component of disaster recovery (DR), as well as for operational backup for applications that require shorter recovery point objectives (RPOs) and recovery time objectives (RTOs) than what traditional tape backups can offer. Firms are also adopting data replication for remote- and branch-office data protection; in a hub-and-spoke architecture, branch-office data can be replicated back to central data centers, thus eliminating unwieldy tape-based backup procedures at the branch sites. The growing adoption of replication services has been driven by a wide array of data replication products, more lower cost replication offerings, faster and...

Less physical data living and moving over our plumbing means we can have more virtual instances of that data, which drives even more value.
Cloud storage is a service, just like what storage service providers attempted to do years ago. But the technology has evolved and this time, cloud storage is real.
Cloud storage vendors might find a silver lining to the current economic cloud as companies try to cut costs. But enterprise storage shops are still wary.
