When using computers as the main tool for your business operations, it is important to back up your data. A good metaphor for importance of remote data replication is having car insurance. 99% of the time you never really need your insurance, but it is that one time you have an accident, even a minor one that you are thankful that you have it. A minor car accident can still cost plenty and so can data loss from you computer network. Losing the data on just one machine can equate to months even years of hard being lost.
The Minimum Needed for Data Back Up.
The absolute minimum needed is a periodic back up of the company's emails. Email is an important form business communications, documents, spreadsheets and files are all moved via email. Backing up email files is important from a legal standpoint also. Emails can be subpoenaed in court and can be a good defense against disgruntled former employees. Unfortunately technology has advanced beyond, most offices now use instant messaging to move files and communicate with little back up.
Remote Data Replication
Remote data replication will replicate all of the data on your network and place it in a remote location. By utilizing remote data replication, companies can be assured that a catastrophe like a natural disaster or a terror attack will not be able to cause a loss of data. Remote data replication is already in place for institutions that need the security of a remote backup, such as banks and financial markets. Before those were the only companies which both could afford to and needed to use remote data replication.
Remote Data Replication Costs
Remote data replication costs have been reduced because of new technologies that use asynchronous replication. The old form of remote data replication was synchronous replication where data would be replicated twice, once to the intended server and the second to the backup location. This was both a time and resource consuming procedure. Now remote data replication is done by application hardware which will back up the data to available storage whenever it is available on the network, it can also send back data at time when the network is not busy making sure that network performance is not affected.
Remote Data Back Up
Businesses recognize that Remote Data Replication, remote backup, site failover and disaster recovery are essential tools for protecting their electronic data. There are many data disaster recover tools on the market. Each data recovery solution is trying to solve key issues like central management, flexible volume selection and efficient use of available bandwidth. When choosing a disaster recovery solution, make sure that includes remote data replication. Remote data replication shortens disaster recovery time, and can help maximize data storage. This is why I recommend choosing a network based data recovery solution. This article will explain more about data recovery solutions and why remote data replication is so important.
While there are various data recovery solutions on the market, all of these solutions can be divided into three basic categories according to where the solution resides:
• Host-based
• Storage-based
• Network-based
Host-Based Solutions and Storage-Based Solutions
Host-based solutions are OS dependent and require an agent installed on each host – an agent that generally has limited OS support. This limits their scalability and increases management overhead as IT must configure and manage its DR solutions per OS and not centrally at the network layer.
Storage-based data solutions are vendor-specific leading to vendor lock-in or increased management overhead as IT tries to manage more than one storage vendor. Vendor lock-in typically eliminates the option of using lower-cost storage media at the secondary site, which would enable a company to contain its data recovery solution costs.
Unfortunately neither of these solutions allows for remote data replication. Remote data replication is the lynch pin in a quality data recovery solution. Without remote data replication the network remains vulnerable to a single point failure. If the data storage center is destroyed or disconnected from the network then all of the data will be offline if there is no remote data replication.
Network-Based Solution - Remote Data Replication
Network based solutions live at the network level. Network based solutions replicate data at the block level providing the most efficient data replication thereby decreasing traffic on network links and resulting in the most up-to-the minute data copies at the secondary site. This is why remote data replication is so important when choosing a data recovery solution. Remote data replication continually backs up data to remote sites so that no single point failure will disrupt the safety of the data.
The importance of Remote Data Replication can not be undervalued. Remote data replication should be the first you look for when solving your data disaster recovery needs.
