Your business is not at war but you do need to defend against adversity and the unexpected.  Every day there is potential for things to go wrong that will stop people working, more so as we embrace and rely on digital technologies.  We have broadly 3 lines of defence against adversity.

1 Resilience

Resilient systems are your first line of defence, they take into account the possibility of failure and have alternatives in place that enable people to continue.  In the best cases people do not even know there is an issue and a fix is made without interruption.  Less ideal there is only a small break in service while an alternative or repair is put in place, see my blog “Be Resilient. be prepared

2 Automated backup

Your 2nd line of defence is you full “automated backup“.  I use automated deliberately, as in our experience the weakest link in an backup process is the person who does it, normally when they are away or on holiday.  In addition automation means backups can be taken at least every hour.  We think it is best to have your backup on site as this is where you are most likely to need it and you have it under your complete control.

3 Offsite backup

Your last line of defence is a copy of your backup securely held in a different location to the systems being backed up.  This copy is your disaster recovery copy  for use in the event of fire, flood or theft; or some unpredictable event that renders your onsite backup unusable.

You can argue there is a fourth line of defence, that is the human element. You need someone to design and setup your resilience and backup systems, but perhaps more importantly, someone has to monitor, check and test everything is working and ready for use.
