Difference between backup and replication

Many of you out there are in a myth that backup and replication are one and same. But in reality this assumption is completely false. Below article has been written to help you understand the said data recovery techniques in a better way.

Backup vs Replication

Backup definition- backup involves making a copy or copies of production data. It either requires disk or tape based solutions and needs some place to store archived tapes. However, with the advent of cloud computing things have changed far better when it comes to archival storage- a topic which will be discussed further in the later parts of this article.

The whole purpose of having a backup copy is compliance and granular recovery such as recovering email data of a user say of five years ago. Basically, the concept depends on snapshot technology where copies of data sets are taken at a pre-determined point in time and stored in an order. Sometimes, old backups get replaced by new backups and in most cases each backup set is treated as a different entity.

All this process ensures that there is zero data loss of critical or production data. However, business continuity is not assured by just having a backup copy in place,.

Replication definition-Replication is the act of copying data to remote appliance or platform. Therefore, replication requires investment in another appliance or identical infrastructure, effectively doubling a company’s IT costs. It is typically measured in Recovery Time Objective (RTO) and Recovery Point Objective (RPO).

The objective behind Replication is to focus on business continuity-offering quick and easy resumption of operations after a disaster or corruption.

Replication can be carried out in a synchronous or asynchronous way, focusing more on those business applications and processes that have to be available after a disaster.

As both Replication and backup are essential for keeping data continuity during a disaster, StoneFly offers solutions related to both these services in its product catalog.
