The DRs of Business Continuity

Posted by Jon Ryan on Jan 3, 2014 4:15:00 PM

Cloud BackupIn the ever changing technology of the digital world, company data has become one of the most important parts of a successful business.  Not only the retention of data but also having reliable access to it. Imagine this scenario: Your business has multiple locations in the Mid-West that access data from a core location. A power grid goes offline due to iced up lines. How does that affect all locations? Are you prepared for this today? Or do you just plan to react to it when it happens? Take into account this scenario: Suddenly you are unable to access your data on your server. With the recent growth of RansomWare (where your data is held hostage by hackers) are you protected, and how do you continue to do business? Or even in the case of everyday hardware failure, are you backing up your data, and if so, what level of redundancy do you have to be able to access it?

It is easy for a business to have a false sense of security when it comes to their data. Having a firewall or anti-virus program is not enough protection from everyday threats. It is absolutely imperative to have a Data Backup & Recovery and Disaster Recovery plan to ensure the highest level of protection. Two of the DR’s of business continuity. Let’s take a look at what Disaster Recovery and Data Recovery really are.

Data Recovery

Probably the most common form of business continuity practiced, Data Backup and Recovery is the most affordable way to protect your business from a catastrophic event. But many people don’t truly understand that there is more to just backing up data than copying it to a network share.

In a typical Data Backup and Recovery solution, the best practice is to write the backups to a local device such as a NAS or External Hard Drive. These backups allow you to take advantage of two levels of protection: server drive RAID failure protection; and local file recovery from an external source. In this example if your server were to crash you would still be able to recover files from a second source.

Any type of backup is better than having nothing, but to achieve a higher level of business continuity you should also have a Disaster Recovery plan as well. What if your building experiences a fire, break in, or natural disaster? Your onsite backup will not be enough to continue operating your business at a normal level. That’s where Disaster Recovery comes into play.

Disaster Recovery

“It will never happen to us.” “What is really the likelihood of a tornado hitting our building?” “I have a hard time justifying the additional cost of Data and Disaster Recovery.” All responses to the question of Disaster Recovery protection.

Disaster Recovery allows companies to save data to an offsite location for just that reason. It is a best practice to save data locally for fast recovery and offsite for disaster recovery. The traditional way to achieve this was to copy data to tape drives and store a daily backup offsite. Cloud technology allows you to get rid of the time and security risk of tape drives.  Now that you have a disaster recovery option and a way to store your data locally and offsite, how do you keep your company processing data with no interruptions in the event you are unable to access your data? 

Data Replication

Data ReplicationIn the ice storm scenario above we discussed multiple locations accessing data from a core business location. If one of the external locations goes down, that location alone is only affected. But if your core server location goes down, all external locations are unable to access the core server data and applications.  The only way to achieve high availability of your data is to replicate it to a second location. 

Data and Compute Replication is a technology that allows you to make a copy of your core server data and applications and place it on hardware at a second site. The second site is usually the site with the best network connectivity the furthest away from the core site. With failover technologies, if the core server goes down, the system automatically fails over to the DR site.  This allows all other locations to continue to access data and applications while the core site recovers from the event. This solution can also act as your Disaster Recovery Data Solution but would also want to be tied to a separate local Data Backup solution for faster file recovery in the event of lost data. 


Now that we’ve given you some ideas and options to improve your business continuity, where do you go from here? A data backup and recovery assessment might be necessary to review your current solution to determine which of the three DR’s you have or need.

Cloud Backup. Is It For Me?

cloud backupThere has been a lot of buzz around “The Cloud,” and whether or not we can push our backups into the cloud in lieu of local tape or disk backups. In many cases this is a viable option, but there are some considerations to keep in mind:

  • How Much Data do you need to back-up?
  • Do you have enough bandwidth to handle sending the backup offsite?
  • Is all of your data centrally located?
  • Do you have roaming clients that need to be backed up?
  • How fast do you need to recover in the case of a disaster?

The amount of data you need to backup is important for several reasons. First, cloud based backup providers commonly determine price based on the amount of data you are storing offsite. Typically there is a point at which the cost of a cloud based backup becomes
prohibitive and the traditional onsite backup makes more sense. This is something you would want to evaluate with whatever cloud solution you are reviewing.

Second, if the cost of offsite backup is within your budget, then we need to make sure that you have the necessary bandwidth to handle sending your selected data offsite on a nightly basis. For example, unless you have a dedicated WAN link to backups, you likely don’t want to be running your back-up 24/7 as this would compete with your normal traffic causing a bottleneck in your network.

cloud backup questions to askWhere is your data located? Is it on one server, two servers, or even across multiple workstations? Along with per GB pricing, some cloud providers also license per endpoint. This mean that for each device you want backed up, you may need a unique license and perhaps even a separate client loaded on each. Although it may add to your cost, this is a good option to keep machines which frequently leave your network backed up.

How much data do you need to restore and how fast? In the case of a disaster, pulling all of your data out of the cloud may not be a viable solution as the speed is dependent on how much data and the bandwidth you have available, therefore keeping a local USB drive to seed a bare-metal restore may make sense. For simple file restores however this is typically a non-issue.

cloud backup strategiesBefore making any decision on a backup solution you really need to identify key business drivers and evaluate what your business cost per hour without it is worth to you. Different backup strategies have different speeds of restoration and your decision should be tied to those drivers.

Network Center, Inc. has a wealth of knowledgeable resources who have evaluated and implemented a variety of solutions and can help review your business needs to determine if a cloud based backup is right for you, and if so, the cloud backup strategy that allows for recoveries within a DR timeframe that works for your company.
