After what type of backup can you resume the incomplete recovery of an SAP HANA tenant database?

The ability to resume an incomplete recovery of an SAP HANA tenant database is specifically tied to log backups. A log backup records all the changes made to the database since the last complete backup. This capability is essential for point-in-time recovery, as it allows you to apply changes logged since the last consistent state of the database.

When an incomplete recovery is initiated, the recovery process uses log backups to replay the changes that occurred after the last full or data backup, allowing the database to reach a desired state. This is particularly important in scenarios where a complete backup might have missed critical updates that were captured in the log.

While other backup types, such as full and external backups, play vital roles in data protection and restoration, they don't provide the incremental change data that log backups do. This makes log backups an essential component for resumable recovery processes in SAP HANA, enabling administrators to restore databases to a specific moment effectively without losing recent data changes.
