Blog: The disaster avoidance power trio – Backup, DRaaS and Colocation

With any backup, it’s always good to keep the 3-2-1 rule at the back of your mind, especially if you want to effectively address any failure scenario. As part of this rule, it is highly recommended you have a reliable partner to take care of your offsite backup in a secure and scalable location – so that you can focus on the more strategic tasks.


About the 3-2-1 backup rule

Ever heard of Veeam’s 3-2-1 backup rule?

Well this Peter Krogh-inspired (a well-known photographer who claimed that there were two types of people: those who already had a storage failure and those who will have one in the future) concept points out how to effectively address any failure scenario, using 3 distinct steps:

  1. Have at least three copies of your data.
  2. Store the copies on two different media.
  3. Keep one backup copy offsite.

These steps also answer the “ye old question” how many backup files should I have and where should I store them?

Let’s dive into these steps a little further.

Have at least three copies of your data actually means on top of the primary data you have.

Why should you have more than one backup? Veeam provides a very good reason:


“Imagine that you keep your original data on device #1 and its backup is on device #2. Both devices have the same characteristics, and their failures are statistically independent (they have no common failure causes). For example, if device #1 has a probability of failure that’s 1/100 (and the same is true for device #2), then the probability of failure of both devices at the same time is:
1/100 * 1/100 = 1/10,000
This means that if you have your primary data (on device #1) and two backups of it (on devices #2 and #3, correspondingly), and if all devices have the same characteristics and no common failure causes, then the probability of failure of all three devices at the same time will be:
1/100 * 1/100 * 1/100 = 1/1,000,000
This is why having more copies of your data means you will have less risk of losing data during a disaster. In short, if your data is important to you, be sure to make at least two backup copies.”

Step number two was store the copies on two different media. The 3-2-1 rule suggests that your data should be stored on at least two different storage types to avoid common failure. This can be for example internal hard disk drives and removable storage media, or even two hard disk drives in different storage locations.

And lastly, keep one backup copy offsite. Physically separating backups is highly recommended, should you be unfortunate enough to experience some type of disaster. The cloud is often seen as a good option.


How Blue Central cones into the picture

To help facilitate the execution of this rule, Blue Central offers a selection of services to effectively address any failure scenario:


1. Backup as a Service: Securing your off-site backup

Think a quick and efficient backup at the end of each day is a slow and painful process?It is… but not if you have backup-as-a-service!

This cloud-based alternative means in an event of an unexpected issue, your business can be up and running again within minutes and with minimal downtime.

And with regular tests and reports to check the validity of backups being done, you can rest easy knowing you’re always up to date.

What’s more, since you don’t have to buy additional media or infrastructure to store your backup data, you only pay for the data you’re protecting, no matter how many copies are being backed up.


2. Disaster Recovery as a Service: An affordable and flexible method for delivering business continuity

When disaster strikes, you need a strategy in place to get your business back to normal. You can save time and costs just by replicating your applications and data via backend storage in the cloud.Disaster recovery removes the need to install complex software because your data is already in place, configured correctly and ready to go. You can choose which data to protect, or protect a whole environment if you need to.

No matter what you choose, you only get charged for the data and storage you want to replicate, not for the compute and network layers.

Great news, you don’t have to operate an expensive standby site!


3. And lastly. colocation – A secure and scalable location for all this to take place

In today’s challenging business environment, companies are experiencing rising demands for IT services, both internally and externally, especially when an existing data center can no longer carry the company’s IT burden alone.In other cases, many companies may require it necessary to establish a secondary site to ensure business continuity.

And just think…


As half of compute moves to the cloud:
  • Expensive data centre real estate becomes underutilised
  • Still need to support and maintain power, cooling, fire infrastructure
  • Must maintain specialist staff skills

An effective and cost-effective solution is colocation.

So what is colocation?


The provision of space for a client’s computing and networking equipment on premises managed (and sometimes owned) by
third-party firms.

As Australia’s leading independent data centre operator with a national network of Tier III faciliaties, NEXTDC provides enterprise class colocation services across the country, enabling hybrid cloud deployments through their Cloud Centre ecosystem – Australia’s largest independent network of carriers, cloud and IT service providers.


So what do you get when you cross Veeam, Blue Central and NEXTDC?


Blue Central leverages Veeam products as part of their DRaaS offering, an offering particularly appealing to organisations with data hosted in the CBD and are looking for a hosted disaster recovery location.And as for NEXTDC?It’s where Blue Central’s cloud lives!
