I would first assess the extent of the loss and identify the root cause. Then, I would use the recovery tools provided by the cloud provider, such as snapshots, backups, or version history. If those do not work, I would consider third-party data recovery services. Meanwhile, I would review the migration process to prevent such incidents from happening again in the future, implement stricter data validation checks, and enhance backup strategies. Open communication with stakeholders is crucial throughout the recovery process.

First and most, make backup copies of everything you´re migrating, at least two copies. One of the copies should be sent offsite. Test the backups. Depending on the RTO, you might want to backup to disk. Also, a rollback plan should be developed in case the migration does not work as planned. Only after confirming that all backups are in place and ready to be restored if needed, you can start the migration.

In a previous migration, I introduced a “sidecar recovery pipeline”: a lightweight, real-time data capture tool running in parallel with the main migration. As data moved, this sidecar service recorded all changes, deltas, and metadata into a secure, immutable storage bucket. When we encountered unexpected loss, we reversed the flow, replaying these captured deltas back into the primary system. By leveraging this sidecar approach, we minimized downtime, ensured data integrity, and gained a reliable backstop for any future migrations.

Cloud migration can be tricky! Having verified backups, responsive support, and a robust disaster recovery plan makes all the difference in quickly recovering from data loss.

- Implement encryption mechanisms - Bucket storage versioning mechanisms - Backup plans together with recovery plans - Classify your data based on sensitivity

Recuperação de dados perdidos: Implemento o plano de backup e restauração previamente definido, recuperando os dados das cópias armazenadas localmente ou em outra região da nuvem.

Cloud migration can be a daunting task and losing your data during this process might be stressful if you are not sure about how to get back your data. First, assess how much you’ve lost and check any backups you might have. Utilize built-in tools like Google Cloud Storage versioning; restore from previous backups (e.g., AWS S3). For more complex situations, consider MyRecover or R-Studio as professional recovery options. After recovery verify data integrity, activate periodic backups, and frequently test disaster recovery plans. Do not overwrite backups during migration, and implement strong security measures such as MFA. With a proactive strategy, risks are minimized and business continuity is ensured.
