Today, March 31, is World Backup Day. This date exists because, even today, I still see many companies continuing to lose critical data. In the vast majority of cases, these losses are not related to a lack of technology, but rather to strategy and process failures, and especially to an underestimation of risk.
And these risks are not limited to lost files or servers with software issues. They involve systemic failures in operations, security, and even architecture.
Real Case
I will cover a real case I went through recently, where I will share more details not only about the problem, but also about how it was possible to recover from the disaster.
The Scenario
In a virtualization environment made up of multiple clusters, a ransomware attack impacted the environment and made a number of virtual servers unavailable. Fortunately (or thanks to good judgment), only one cluster was affected.
Containment
In parallel, the entire security team immediately began working to understand the incident and to carry out containment operations so the issue would not spread to the other clusters. Once that stage was overcome, we had a scenario where it was already possible to begin restoring from backups.
Backup Restore
Given that we already had a secure and controlled environment, and with the dates of the backup restore points that needed to be restored, the restores began. The most important point here is to be sure the backup you are restoring is clean and safe. After the environment is secure and resilient again, you cannot put the environment at risk by restoring a server or data that was already infected. In these cases, there is a very high chance of being infected again.
How to Ensure a Clean Restore
Backup and data protection solutions must be able to ensure that the backup stored in the repository is clean and free of issues. Veeam can ensure this through the Threat Hunting feature. Even so, it is also very important for the security team to perform a second, independent verification as well.
Restoration Plan
After that, the restoration plan was started. At that point, it was already known that the backup was intact and restorable, because several prior checkpoints had been reviewed and revisited. Best practices were being followed:
- Immutable and isolated Linux repository
- Automated restore testing with SureBackup
- Manual restore testing aligned with the business
- Isolated backup network
With all of that in place, the restores began. Multiple approaches were used: Instant Recovery, full VM restores, granular file restores, etc.
Conclusion
This made it possible to recover from a disaster that could have been much worse. At the end of the day, the value of a backup strategy is not in the technology implemented or in the number of jobs configured, but in the real ability to recover when everything goes wrong.
The case presented makes this clear: success did not come only from having backups, but from a set of decisions executed over time. Segmented architecture, protected repositories, continuous validation, and, above all, preparedness for a crisis scenario.
Ransomware, human error, and operational incidents are no longer exceptions. They are expected events, but you do not know when they will happen. The difference between a controlled outage and a large-scale disaster is directly linked to the maturity of your data protection strategy.
