You can use an SAP HANA database snapshot to clone a database while it is running using the underlying storage system. This use case ensures a consistent point-in-time database by creating a database-internal snapshot file from SAP HANA, which is then stored in the data area. An SAP HANA storage snapshot consists of all the persisted data in the data area. For this reason, the files and directories under the mount point of the data area must all be included in the storage snapshot.
This use case describes the steps that are required to set up and establish clones of the R2 devices at the remote site for test, development, or QA purposes using SnapVX.
The following figure illustrates a scenario where production is running at the source site and the production data (on R1 devices) is replicated to the target site (R2 devices). Meanwhile, SnapVX linked targets containing the SAP HANA storage snapshot of the R2 devices are used to start an SAP HANA database at the target site for development, test, or QA purposes using a SnapVX snapshot.
