The first step towards putting a disaster recovery plan in place involves copying all mission critical data offsite. In the event that a catastrophe should occur, a business won’t lose so much as a step because that information can then be directly copied back to hardware and business can resume in earnest. One of the issues that many businesses face, however, is one of data movement. Exactly what is the most efficient way to copy a huge amount of data offsite and then back again when the time is right? There are a large number of different options when determining data movement for disaster recovery – not all will provide the type of performance that is needed in those most importance of moments.
Data Movement Failures
When determining the best method to move data from Point A to Point B and back again, one issue that many businesses face is one of data loss. The chance of data loss is unfortunately high during data movement, which results in essentially the exact opposite of the intended situation.
Secondary Hard Drives
To combat these types of issues, many small businesses in particular are prone to just copying their information to an external hard drive on site and transporting those drives offsite for more permanent storage. Not only is this efficient, but it’s also cost effective. There is no guarantee on long term shelf life of these types of drives, however, which is where one of the major issues comes into play.
The cost of a tape drive can quickly exceed $2,000 depending on your performance and capacity needs, which is why many small businesses tend not to experiment with these techniques at all. A hard drive technology like RDX or even cloud storage could be much better, more viable alternatives.
The Enterprise Strategy
If a business has more than one location, they need to worry about two different types of data movement: data that is being moved to meet immediate disaster recovery needs and data movement to help store things for the long term.
Data that is being moved to restore applications can be handled using technology like primary storage replication, for example. Secondary storage systems should also only be storing the most recent copy of data and should overall only be retaining a very small amount of information. Older data should then be moved to the cloud or to a tape-based system to not only help manage data movement in a more cost effective way, but to also help keep up with the demands of compliance.
