Disaster Recovery and Restoration – Data Backups
Let’s talk about disaster recovery in general. DR is far more than just copying your information to an external media like tape, hard drive, or perhaps a cloud-based disaster recovery data center. If you really want disaster recovery then you need to have off-site, duplicate. I was talking to a Boise roofing contractor that said he offered two different local businesses the same deal on a new roof for their storefront. One business owner said “No, we’re good for another couple of years – we’ll pass.” The other business owner took up the roofing contractor on his offer and had his roof redone with TPO.
It wasn’t 5 weeks into winter when the roof gave out (due to dampness and heavy snow accumulation) for the business owner that didn’t take him up on his offer. The snow that fell through the roof onto the computer terminals was enough to fill the back of a pick-up truck and it slowly began to melt. It sat on the store owner’s computer system for about 12 hours before someone alerted the shop owner to the roof collapse. – He lost everything from his tower, his monitor, and yes – even his backup external hard drive that was now covered in 4 feet of snow. So do yourself a favor and get an offsite backup.
The duplicate IT infrastructure might differ in quantity and level but at a minimum you should have sufficient resources to run all your company critical application and provide access to all of your business crucial data for an indefinite time period. Your data ought to be replicated every day to the cloud based or private cloud disaster recovery place and you require reliable remote access to these sources.
We will briefly describe the five DR types in this post but leave the detailed descriptions and discussions for the following articles. In the last article in this series, we will discuss company continuity in much more detail. Information backup is the procedure of creating a copy of one’s information files on an additional media.
Depending on how much information you have, you can accomplish this process by copying your files to a thumb drive, external difficult drive, DVD, tape, another pc, or to an off-site place in the cloud (cloud backup). You can also backup important files to one media set and then all your files to a cloud backup. This would permit fast, off-line access to essential files on say a thumb drive while nonetheless having a total set of files available should catastrophe strike.
There are lots of pitfalls to backing up your information correctly that we’ll continue to cover in following articles. Cold DR is when you have your mission crucial servers duplicated and your information replicated; all in an off-site information center. Data replication usually occurs every day but might be more frequent.
The servers are not actually turned on so they are not using resources on the data center hardware. Switch over may take a complete business day so you can be with out access to your applications and information till everything is totally up and running. This is usually the least price disaster recovery approach.
Data backup (Backup) – disaster recovery (DR)
…and company continuity (BC) are a few of the most misunderstood ideas in Information Technology. Just like the roofing contractor Boise that we mentioned above – you’ll want to make sure you’ve taken all precautions – even the ones that might not ever happen. Because if they do happen, then you’re too late.
There are many misconceptions and myths surrounding Backup, DR, and BC. We’re going to define and talk about these important ideas in this series of articles. We’ll also talk about the significance of having a company disaster recovery plan and a business continuity strategy, as well as testing your plans.
What’s a disaster for the company? There are many issues that can be disastrous for your company. We define a disaster as any occasion that prevents you from operating your business inside a regular manner. Many occasions we consider fire, tornado, hurricane, earthquake, etc. As disasters. But disasters are available in many sizes and levels of severity. We had one client that known as about a flooded developing that was condemned by the fire marshal.
The flood was brought on by a faulty sprinkler system on the 3rd floor that caused water to flow through all 3 floors of the developing. Another client known as about an overflowing toilet that flooded their suite.
Yet another client known as about a complete energy and data failure to their developing brought on by a backhoe at a neighboring building website. And after that there is the disaster of one’s system crashing to the point of losing everything on the difficult drive and your information is unrecoverable. All of these are examples of disasters that are localized to a single building, a single suite in a building, or just your business’ I.T. division.
Disaster Recovery – Testing and Updating
Based on numerous professional sources such as Gartner, PricewaterhouseCoopers, and the University of Texas, 70% of businesses that encounter a significant information loss are out of company within one year and 94% of businesses suffering from a catastrophic information loss don’t survive. With those sorts of odds it’s like betting your business in Las Vegas in the event you don’t have some type of disaster recovery in location.
Warm DR is whenever you have your mission critical Servers duplicated as well as your information replicated; all in an off-site data center. Data is typically replicated 4 or more times per day. You might also have some additional non-critical servers duplicated in the data center. The servers are really running and accessible so switch more than is quicker and will generally only take a few hours to finish. This DR approach usually costs much more than cold DR.
There are two of the most overlooked components of disaster recovery and business continuity; testing and updating. Most businesses undergo the expense of developing DR and BC Plans then place them in a binder and pat themselves on the back that they have completed the process. The subsequent time the plans are looked at is when a disaster has struck. This really is the worst time to get the plan out and evaluation it; people are not familiar with what they ought to do and many occasions current configurations are not addressed or holes in the plan are discovered. Getting DR and BC plans is a living procedure that ought to be revisited quarterly but a minimum of annually.
