Why You Need to Be On Guard for Potential Data Loss

Why You Need to Be On Guard for Potential Data Loss


What would happen if a major retailer that you’ve been doing business with for 10 years suddenly had no record of your purchases?  Imagine if the VIN on your car didn’t show up in your car manufacturer’s records?  What happens when you go online to place an order and the site is down? Are you a loyal customer that waits for the site to come back, or do you move on and buy the same product from another business?

Your answer to these rhetorical questions can help you get a feel for how crucial it is that data  be continuously available.  When you lose data, you lose business.

In our modern big data era of advanced analytics, businesses now store a lifetime’s worth of data for each and every consumer, manufacturer and distributor. The majority of this data resides in databases such as Oracle.  One of the more commonly used technologies to protect those databases is Oracle’s Data Guard.  There are many solutions that exist for replicating data to another server or to another site, but none can come close to the seamless functionality that Oracle Data Guard provides.

Oracle Data Guard replicates your database data to another Oracle Database server. This server can be stored locally or be placed at a remote site for disaster recovery purposes.  The beauty of using Data Guard as opposed to other replication solutions is that since it’s fully aware of what is going on with your database data, it can protect you from data corruption. In block- based replication solutions that operate differently from Data Guard, corrupt data will be replicated just as freely as healthy data. The non-Oracle replication technology has limited or no protection mechanism against corrupt data. Data Guard provides that additional layer of protection.

Another great feature of Data Guard is that it fully integrates with Oracle’s Cloud control, giving you a high level application view of your replication. This integration also allows you to easily swap over to your standby server and then back again with a few simple mouse clicks or commands.  As a bonus, Oracle Database Enterprise Edition includes Data Guard. There is no additional charge for (the word “standard” here may confuse people….the word standard usually implies a version of Oracle that does not include Data Guard. The phrase “standard data guard” would be considered a contradiction by many people.) Data Guard.

An added option to Data Guard is Active Data Guard. What Active Data Guard does is allow you to use your non active server for other data operations such as analytics or other reporting. In this scenario you don’t have to feel that your standby server is an unutilized resource.

If you are like most businesses, you can’t afford to lose data, or you may lose customers – or worse. Oracle’s Data Guard is a cost effective and native replication technology that can protect your data and simplify the management of your replication. When staring at potential data loss people often are in a panic and not thinking clearly. Without Data Guard you may have to enter many cumbersome commands that could make things worse. Data Guard removes that uncertainty and gives you one easy mouse click to stabilize things. If you have any questions about database protection in general or Oracle Data Guard, please contact us.
