Can you restore your physical and virtual servers after a disaster?
In today’s data-driven age, for any business, storing, accessing and maintaining data is critical.
To the modern business, data is the crucial element that carries information to those business functions that consume it and as an organisation’s most valuable asset; it is imperative that your data remains accessible, manageable and protected at all times.
But what happens if the worst occurs? What happens if either a man-made or natural disaster cripples your IT infrastructure and stops your business operating?
Every company should have a disaster recovery plan in place. A disaster recovery plan provides a structured approach for responding for unplanned acts that threaten your IT network and infrastructure – including, hardware, software, networks as well as people and processes.
For any business, in the event of a disaster, your priority is to get your business back up and running as quickly as possible. If you've lost your server, either physical or virtual, you will have to spend valuable downtime setting it up and configuring it before you can restore your data.
When restoring data, quantifying the amount of data loss is vital.
The terms for quantifying data loss are Recovery Point Objective (RPO) and Recovery Time Objective (RTO).
- The RPO is the longest acceptable time period over which you can tolerate losing data. If your RPO is one hour, then your data should be backed up at least every hour.
- The RTO is the longest time that’s acceptable for restoring operations.
Disasters are often complex, so the ease of restoring your data often depends on how well you have prepared and what precautions you have taken. Here we have discussed data recovery in both a physical and virtual environment.
Disaster recovery in a physical world
Traditional methods of recovering from disasters have often relied on moving backed up data to suitable hardware - generally at a designated disaster recovery centre. Physical servers at the disaster recovery location are prepped for use and are ready for back-up data to be restored to them. Moreover, the benefits of backing up your data to a specialised data recovery site means that the site itself will often have its own resources such as physical security, support staff and fire suppression – a result of which means your data is at a lower risk against cyber criminals and your data can be accessed quickly and often can be restored quickly.
Yet purely backing your data up to a physical location can often bring logistical and economical challenges. The hardware at the back-up site needs to be configured and updated in sync with your own previsions and this is often a time-consuming and expensive task. Moreover, this can also be problematic for larger organisations with lots of servers.
Disaster recovery in a virtual world
When using a virtual-based approach to backing up your servers, you’re able to use a cloud provider’s data centre as a recovery site. The advantage of having your disaster recovery in a virtual environment often means that recovery protocols can become automated and don’t require human intervention. The benefit of which allows you to replicate your data at regular, pre-defined intervals over a wide-area network to a second server and storage environment at a specified data centre.
Moreover, using a virtual-based disaster recovery solution negates the need to reconstruct a physical server in the event of a disaster. It also means you are also able to achieve your targeted recovery time objectives (RTO) more easily by placing a virtual server on the cloud.
