For any business, backup and replication are two essential attributes which are analogous in most aspects except for 2 technical parameters that defines their difference. In common, both backup and replication aim at providing disaster recovery. But in contrary, RPO and RTO are two parameters that differentiates backup from replication.
Recovery point objective(RPO):
Recovery point objective defines the frequency at which a production environment is being backed up. In other words, the time interval taken between consecutive backup schedules. RPO signifies the amount of data that can be lost in time taken between two successive backup schedules.
Recovery time objective(RTO):
Recovery time objective is defined as the time required to reconstruct the production environment to get it up and running in case of a disaster. In short, the maximum time period a business can withstand without a live production environment in case of a disaster.
Businesses should be aware of their requirement of RPO and RTO to define best setup to choose: either backup or replication.
- Businesses dealing with big data and large data transactions continuously can’t afford downtimes, their expectation of RTO will be ideally zero seconds; In such cases, replication comes as the better option than opting for backup.
- On the other hand, intelligent backup offers high security for redundant business data with customized restore options. It also offers multi-file restore options which helps in cross platform migrations like physical to virtual (P2V), virtual to physical (V2P) and physical to physical (P2P) between VMware, Hyper-V and physical server environments. But RTOs become significantly high for backups, which is not affordable for data critical businesses.
High availability via Live replication:
In information technology, high availability refers to a system or component that is continuously operational for an indefinite period withstanding disasters. Live replication can ensure high availability efficiently for businesses where RPOs are ideally minimum and replication ensures a point-in-time copy of production environment is ready for use at any time.
