This is our second post in our series on performance tuning with Apache Cassandra. In the first post, we examined a fantastic tool for helping with performance analysis, the flame graph. We specifically looked at using Swiss Java Knife to generate them.

Data is critical to modern business and operational teams need to have a Disaster Recovery Plan (DRP) to deal with the risks of potential data loss. At TLP, we are regularly involved in the data recovery and restoration process and in this post we will share information we believe will be useful for those interested in initiating or improving their backup and restore strategy for Apache Cassandra. We will consider some common solutions, and detail the solution we consider the most efficient in AWS + EBS environments as it allows the best Recovery Time Objective (RTO) and is relatively easy to implement.
