What is Disaster Recovery

What is Disaster Recovery?

Disaster recovery is a plan to anticipate potential problems and/or disasters that could happen to your IT systems, networks, infrastructure, communications, and data. This could be as a result of a natural disaster such as flood or as a sustained attack from Cybercriminals. Having a Disaster Recovery Checklist in place will save you a great deal of time whenever Disaster Recovery Planning is required.

The aim of Disaster Recovery is to get your I.T systems back up and running as soon as possible allowing you to continue to work.

Some of the possible disasters that you should consider preparing for:

• Hardware failure or software corruption.
• Virus or hacker attacks.
• Internet connectivity outage.
• Natural disasters, such as flood, hurricane, tornado, earthquake, etc.
• No access to your office building (crime scene, pest infestation, fire, etc.).
• Theft of physical devices (server, workstations, laptops, etc.) or data.
• Human error (erasing data accidentally or intentionally).

When thinking about implementing a disaster recovery checklist and subsequently a disaster recovery plan, it is important to ensure that your Cybersecurity and overall IT Security policies and procedures are documented and replicated once the disaster recovery has been implemented.

Some of the mistakes that companies have made when thinking about disaster recovery:

Still using outdated and problematic backup methods?
It was not that long ago that companies were still using tape to back up their systems. In fact, some of the larger players still use tapes today. They routinely put the tape backup in and assumed that just because it finished, the backup was successful. Unfortunately, however, very few companies ever check that the tape worked – often relying on the “Verified” message from the backup software.

100% of tapes failed at some point. Major issues with using tape include: The tapes stretch and become unusable. The drives themselves fail as they were often susceptible to heat and magnets and of course, the tape drive data was not always encrypted.

This soon moved to external Hard Drives, which best practice suggests were rotated every day after the previous night’s successful backup. Although by no means perfect, they were miles ahead of tape drives. Hard drives could be encrypted through software such as bit locker, were much easier to verify and test restore data from and were much more robust in terms of daily usage. Although, hard disks were still very susceptible to failures.

Offsite cloud backups are one of today’s best ways to backup your data. Not only is the cloud secure and encrypted, its also off site and not affected if something should happen to your premises. Utilising cloud backup often proves instant access to files should the need arise, without struggling to find and plug in an external HD. Additionally, cloud backup is scalable, in that you only pay for the data usage that you have used and as its internet-based, it can often be restored quickly.

What elements are part of an overall Disaster Recovery Checklist and Disaster Recovery Plan:

• Document your hardware & software applications. Know what you have as part of your company IT infrastructure and where to find it in the event of a disaster.
• Have a documented backup plan. Where is everything stored, who has access to it?
• Document your security strategy. Who has access to the passwords? Who can access the files and folders?
• Recovery Time Objective (RTO). How long to recover the data.
• Recovery Point Objective (RPO). How far back are you willing to go for an acceptable restore date and time.
• Maximum Acceptable Outage (MAO). This is the maximum amount of time-critical business functions and data may be unavailable. This encompasses all activities from the point of the disaster happening to the point of recovery.
• Hardware / Vendor documentation. In the event of a total loss, where would you purchase your replacement hardware from? Workstations, Laptops, Servers, etc. This would also include infrastructure such as switches and routers.
• Telecoms Provider information.

As part of your Disaster Recovery plan, you need to be ready for any of these scenarios also:

• Complete or total loss of your office building or the ability to access it
• Fraud, cybercrime attacks, theft or vengeance from a disgruntled employee
• Death or complete disability of a senior executive
• Complete loss of power, utilities or Internet connectivity for extended periods of time
• The protection and restoration of critical business FUNCTIONS (not just data)
• Oversights in your data backup (web sites, 3rd party cloud applications, overlooked PCs, etc.)
• Restoring your IT systems if EVERYTHING is gone due to a fire, flood, etc.
