It’s not an industry standard term yet, but Pre-recovery is the best and latest technology on the market to minimise IT downtime. The industry accepts that a disaster recovery supplier will recover your systems for you once you’ve had an IT disaster. Plan B Disaster Recovery however, believes this is an antiquated approach and puts your business at risk of long recovery times. It’s far better for your systems to be recovered in advance of when you’re going to need them – a term called ‘Pre-recovery’. It reduces recovery times and guarantees your systems will be recovered successfully.
But how does it offer these benefits? It’s probably best to start with what happens when systems are recovered. When we reconstruct a machine during a recovery, we reconstruct an image of the machine, make changes to IP addressing and then ensure the recovered machine incorporates these changes. We then test the applications and read the error log. In tests we’ve carried out we see tens to hundreds of errors during a first recovery which all need working through to ensure a successful recovery. The trick with Pre-recovery is this has all been done in advance, meaning hours of work (which adds hours onto your recovery time) can be negated. Our clients with over 10 servers see a recovery time of 30-40 minutes instead of 4-8 hours (and even this may not be business as usual which it is with Pre-recovery).
Pre-recovery also ensures your recoveries a guaranteed. A rigorous testing process, which can be performed daily on a Pre-recovered system, ensures that the errors are reduced to zero and checks that the machines come up within rank order. Because the Active X directory needs to be ready for Exchange to work for example, it’s important that the infrastructure is sound, in addition to the applications and data being fully configured and tested.
Pre-recovery is fast becoming the expected method of disaster recovery as it is the only way to meet demands on recovery time and 100% success rates.
