The benefits of Cloud-managed networks technology that we have felt until now have had a significant impact. No wonder this technology is widely used in various fields such as business and finance. Cloud, which allows users to store more data with larger storage, can also be relied on to access data at any time. Surely this method is much more profitable than having to store data conventionally on certain hardware, right?
Apart from these practical reasons, one more benefit that the Cloud network management offers but not conventional storage is the disaster recovery feature. This feature is certainly needed by anyone, considering that data is important for the continuity of the company. As we know that disasters can come at any time, it is important to protect your data, so you need this disaster recovery feature.
Talking about disaster recovery, two definite terms often appear, namely Recovery Point Objective (RPO) and Recovery Time Objective (RTO). Because they are similar, it is not uncommon for both of them to be considered the same, but different. Here are the differences.
Recovery Time Objective
When a disaster strikes and results in all data being lost, your data center will automatically try to recover from the disaster so that it can resume its IT functions so that it can run normally. So, the time needed by each service product for this recovery is different. this is what is meant by recovery time objective.
So in other words, the recovery time objective is an effort to adjust the time related to how long a product service can run normally after a disaster occurs. As the saying goes, time is money, the sooner a service can perform a recovery, the better. Especially for large companies. Every second count, right?
Of course, this will have an impact on the price you have to pay. The sooner you want the service to recover, the more expensive you will have to pay. For example, if you want a service to run again five hours after a disaster occurs, then you have to pay many times more than a recovery that takes five days, for example.
This is because the shorter the time requested, the more resources required, resulting in higher costs for the procurement of these resources.
Recovery Point Objective
It is different from the recovery point objective. Although this one is often considered the same as the recovery time objective, it is far different. If the RTO is more oriented towards the length of time for disaster recovery, the RPO is more about the data. The recovery point objective is the maximum time that can be tolerated when data loss occurs.
For example, during a disaster, how much data loss can you tolerate? Is it two hours of data, or one day of data, or one week of data? The data capacity within days is called RPO. Quite different from RTO, right? This RPO is closely related to the frequency of the backups you perform. The length of time the RPO affects your periodic backup schedule. Suppose that the RPO time you specify is 24 hours, then you have to do a backup every 24 hours and if it’s less, that means you also have to do more as you backup.
