Backup Power, Backup Data Path, Disaster Recovery Plan

Backup power supplies are essential to protect your network

3. Have a backup power supply - and monitor and test it to make sure it's in working order.

Loss of commercial power is probably the most common cause of network outages. Make sure your power supply has several layers of redundancy: dual battery plants, uninterruptible power supplies, backup generators, backup fuel tanks. Test your backup power sources regularly, on a weekly or monthly basis. Monitor every layer of your backup power supply to make sure it's always available in an emergency - your final levels of defense have to be the most reliable in your system.

4. Have an alternate data path for transporting alarms in case the primary network fails

In too many networks, the only data path for transporting network monitoring information is the network being monitored. If the network fails, your monitoring is lost with it. You most need reliable, real-time alarm data when your revenue-generating network is down. It's an essential best practice to have an alternate data path in case the primary network fails.

Are you ready to recover from natural disasters?

5. Create a disaster recovery plan and make sure your staff knows what to do in case of a natural disaster.

A lot of network outages are caused by natural disasters beyond your control - but being able to recover quickly from a disaster will have a huge impact on your average reliability rate.

Your disaster recovery plan should include:

  • an analysis of the natural disasters that might occur in your region
  • a prioritized list of the network systems that will be affected by a possible disaster
  • established procedures for repairing critical systems under disaster conditions
  • an inventory of essential spare parts and supplies for disaster recovery

That's just a short list - your actual recovery plan should include much more.

Once you have your plan, don't let it sit in a file drawer - drill your staff on disaster recovery procedures regularly. If the worst happens, you want your recovery to run like clockwork.
