Creating an EDI Disaster Recovery Plan

Recent natural disasters striking the southeast and west coast, such as hurricanes and wild fires, have not only taken a huge toll on individuals, but many businesses as well.

These events remind us how important it is to have a disaster recovery plan for your EDI system in place to minimize loss in productivity in the exchange of important documents such as invoices, POs, Shipment Notices and more. Often, the EDI portion of a company’s IT disaster plan is overlooked. EDI systems differ from other computer systems and should have their own recovery plan.

Waiting for a major disaster is not a good plan. It’s not only the major natural disasters such as flooding, fires and hurricanes that need to be planned for, but also smaller scale events like the road crew outside of your company that severed power and communication lines. If your EDI goes down you risk the loss of the audit trail, transaction authorization, data security and transmission security. This downtime can be disastrous for your company. An additional risk can be bridging applications which can integrate all computerized functions of your company such as accounting, inventory control, production systems, etc. A strong disaster recovery plan needs to be comprehensive and should take into account other plans which will be executing at the same time. A well thought out plan, involves a knowledgeable team and solid documentation.


There are five steps that should be considered in an EDI disaster recovery plan.

  1. Emergency Procedures
    This step initiates the initial response to a disaster. You need to assess the damage caused by the disaster such as: what is your current level of stock, number and type of EDI messages that may have been affected as well as the impact to your trading partners. During this step is very important that you are prepared to communicate clear and accurate information to those in your EDI network. You should also have in place a call list of who is responsible for what as it relates to your EDI system. You should also have alternative methods (land line, cell, fax) to make that contact in case your primary methods (office number, email) are unavailable due to the disaster.
  2. Back-up Plan
    Your back-up plan may be as simple as initiating manual system for low-volume, non-critical items to a full switch to a new VAN from a rented hot site for larger volumes. A change of delivery of EDI documents should be reviewed and accepted by your EDI trading partners as well. Also to be considered is if the disaster originated at the supplier, the back-up plan could include the selection and certification of back-up vendors.
  3. Recovery
    This step determines your ability to recover critical information in an acceptable amount of time and making your EDI system operational. This could vary depending on the integration of your EDI system. Considered should be the assurance of retrieving historical data prior to the disaster as well as the level of cooperation of your trading partners, both up and down the supply chain.
  4. Testing
    This is vital step to your EDI disaster plan. It allows you to discover and eliminate any potential problems that may appear and allows you to make modifications before the plan has to be put into action. Various forms of disaster scenarios should be considered during this step. Practicing your execution of the disaster recovery plan when stress and tension of lost business is not pressing can help you determine its viability. This way when the disaster arrives, your team is not executing the plan for the first time and finding out when it is too late, that important steps as missing.
  5. Maintenance
    Your EDI plan needs to be continually updated as you add new trading partners, update operating systems, IP Addresses or DNS names. Your plan should be reviewed yearly to determine additional potential risks as well. This yearly audit assures that your company is protected and prepared, and confirms that the key players understand their roles.
