Introduction

Data replication is the process of copying and storing data in multiple locations to improve data availability and accessibility across a network. The result is a distributed environment that enables local users to access the data they need faster,and without disrupting other users.
Data replication is a key component of disaster recovery (DR) strategies,as it makes sure an accurate and up-to-date copy of data always exists in case of a system failure,cybersecurity breach,or other disaster - whether naturally occurring or through human error.
Copies of replicated data can be stored within the same system,in onsite or off-site servers,or in multiple clouds.
Data replication is key to business resiliency because data drives decision-making. It feeds into and informs mission-critical processes,analytics,systems,and - ultimately - business insights. You want to ensure that it is always available and accessible to users in as close to real-time as possible. Data replication can help you achieve this.
