Asynchronous Replication
In our information-driven economy, it could be said that the value of the data stored in a company’s storage servers or corporate data center is greater than the value of the storage servers on which they reside.
Often, however, this fact is not realized until after a disaster such as a power outage, tornado, flood, or fire strikes… and an organization experiences first hand how the loss of data is even more catastrophic than the material loss of goods. In many industries, in fact, the loss of data on a large scale could signal the end of a company in its present form.
The best response to this vulnerability is to accept responsibility for the need to protect data and take the needed steps to protect it.
With this in mind, it is imperative to create a system for copying valuable data and backing it up, with the added step moving it to an offsite repository when needed, to guard against the original data’s loss or corruption.
This process, known as Data Replication, can take many forms and is a very effective safeguard. However, to understand the full value of replication to a business, it is necessary to first understand the process of leveraging replication as a means of business continuity.
In general, two major modes of replication exist: synchronous and asynchronous replication, with multiple flavors of each between them - including Snapshot Assisted Replication (SAR) and Journal Assisted Replication (JAR), both featured in StorTrends iTX Data Storage Software.
Each bring to the table with their own strengths and weaknesses, and the ideal solution lies in combining them or selectively utilizing the right method at the appropriate time to leverage the cost and performance benefits of both.
