Aws backup and disaster recovery9/2/2023 ![]() ![]() ![]() This is the entire furnace from our example. The application and caching server replica environments are created on cloud and kept in standby mode as very few changes take place over time. This core area is the pilot from our gas heater analogy. The database server on cloud is always activated for frequent or continuous incremental backup. In the preparatory phase your on premise database server mirrors data to data volumes on AWS. Just as in a heater you have a small flame that is always on, and can quickly ignite the entire furnace a similar approach can bethought of about your data system. Pilot Light Approach: The name pilot light comes from the gas heater analogy. Now when a disaster strikes, EC2 (Elastic Compute Capacity) instances in the Cloud using EBS (Elastic Block Store) coupled with AMIs can access your data from the S3 (Simple Storage Service) buckets to revive your system and keep it going.Ģ. Once your backup mechanisms are activated you can pre-configure AMIs (operating systems & application software). However if your data is mostly static with a low frequency of changes, you can opt for periodic incremental backup. For example, if you have a frequently changing database like say a stock market, then you will need a very high RPO. AWS offers AWS Direct connect and Import Export services that allow for faster backup. Backing up of data can be done through various mechanisms and your choice will be based on the RPO (Recovery Point Objective- So if your disaster struck at 2 pm and your RPO is 1 hr, your Backup & DR will restore all data till 1 pm.) that will suit your business needs. Backup and Recovery: To recover your data in the event of any disaster, you must first have your data periodically backed up from your system to AWS. 4 standard Approaches of Backup and Disaster Recovery using Amazon Cloud:ġ. To all these cloud provides a seamless transition reducing cost dramatically. You would also be under utilizing severs and in times of unpredictable traffic rise it would be strenuous to set up new ones. Imagine the kind of cost you would entail in buying and maintaining servers and data centers, providing secure and stable connectivity and not to mention keeping them secure. And if you think about it, it’s really not that surprising. For each business service, customers need to establish an acceptable recovery point and time, and then build an appropriate DR solution.’īackup and DR on Cloud reduces costs by half as compared to maintaining your own redundant data centers. As AWS says, ‘Disaster recovery is a continual process of analysis and improvement, as business and systems evolve. Creating backups of our data to an off shore data center, so that in the event of an on premise failure we can switch over to our backup, is a prime focus for business continuity. Our data is the most precious asset that we have and protecting it is our top priority. It is not only any natural calamity such as an earthquake or a flood, it can be any hardware or software failure, a network or power outage, physical damage to a building like fire or human error. What happens when you don’t have the right DR system ! What is a disaster?Ī disaster can be defined as any phenomenon that disrupts business continuity. If you understand the basics of cloud computing, and want to know how you can protect your data from a disaster, to ensure business continuity you have come to the right place. Enterprises use a mixture of these techniques. This blog offers an introduction to the 4 types of Backup and DR solutions that AWS has to offer. What can I expect to learn from this blog? ![]()
