Oracle Data Guard and Active Data Guard (Part 1): High Level Data Protection

Automatic Updating of a Logical Standby Database.

Just how important is disaster recovery for your business?  Any business would need to protect its assets, and your most important asset is the data you collect about your customers, your competitors and your operations.  Any failure in your system, component or site can be very expensive.  Data corruptions, application downtime and human error could mean lose of sales. It can also result to more business expenses and other non-monetary implications such as negative publicity, bad customer experience and non-compliance with industry and governmental rules and regulations.

The thing is, businesses should be protecting their data from data loss and ensuring that their applications have constant access to this data at all times.  This is taken care of with a good disaster recovery solution.  However, most businesses are putting disaster recovery solution in the backseat.  Maybe this is because they think that a crippling disaster would never happen to them, or for those that who do consider such an event, they think that the disaster recovery systems are too much of a hassle and too expensive for something that they would use very rarely.
