Which types of backups can be used to copy an SAP HANA tenant?

The correct answer is that a data snapshot can be used to copy an SAP HANA tenant. In the context of SAP HANA, a data snapshot refers to capturing an exact point-in-time image of the database, which can be particularly useful for creating a backup of tenant databases or for cloning purposes. This snapshot will contain all current data and can be utilized to restore or replicate the environment as it was at the moment the snapshot was taken.

Data snapshots are beneficial for managing multi-tenant environments in SAP HANA, allowing for quick archiving, replication, or migration of entire tenant databases without impacting the performance of the active database. They provide a flexible solution that can cater to various needs, from disaster recovery to development and testing environments.

In contrast, full database backups, incremental backups, and log backups serve different purposes within the SAP HANA landscape. A full database backup captures the entire database at a specific time, while incremental backups only store changes made since the last backup. Log backups are used to record changes for recovery purposes, allowing the database to be restored to a specific point in time. While these options are essential for backup strategies, they do not function in the same way as a data snapshot for copying a tenant.
