Disaster Recovery: How to achieve extremely high availability with RPO and RTO close to zero

If your company is very dynamic in the area of data and it changes very quickly, you have probably already thought about how you can protect yourself against data loss. The availability of data is particularly important for critical applications and, in the event of a disaster, the reduction of RPO and RTO to a minimum.

How do we keep RPO and RTO equal to zero?

If an IT system or data center fails, no data should be lost if possible. The goal in many companies is to keep RPO (Recovery Point Objective) and RTO (Recovery Time Objective) very small or bring them to zero. (RPO is the length of time that you can tolerate data loss in the worst case. RTO is the time period for a recovery of the data. If availability plays a major role for your company, then RTO should also be close to zero.) The solution for this is Continuous Data Protection. To do this, we combine a VMware platform with a backup solution section that was specially developed for this purpose. At the heart of this solution is a continuous series of recovery points from backed up data.

This is how we protect you from data loss

For continuous data protection, our customers' IT systems run in a shared, dedicated or hybrid cloud in our data centers. Every writing process of data in the storage is immediately transferred to the backup. This means that there is almost no data loss in the event of a disaster, as the backup takes place continuously and not only at a defined point in time, as is the case with conventional backup solutions. All changes or writes are saved in a journal file for a certain period of time. In comparison, a snapshot-based approach offers fewer recovery points depending on how often snapshots are taken (e.g. every 4 hours). You can therefore restore VMs to any point in time or fall back on the last clean copy in the event of ransomware or damage.

Continuous data protection is part of our VMware platform. The feature does not cost anything extra, but serves as a kind of insurance: Hopefully you never need it, but if a disaster strikes, this feature is priceless.

When does continuous data protection make sense?

Switching to a VMware platform always makes sense if your company has a large number of transactions taking place in a short period of time, if high availability and performance are important for productivity and data loss would lead to major losses in day-to-day business. With Continuous Data Protection you can ensure that no data is lost and that data recovery only takes a few minutes after a crash.
