If the data in the logical NVDIMMs has changed since the last Scalable Persistent Memory backup operation and the data has not been backed up using other means, the changed data will be lost.
The logical NVDIMMs (configuration and data) from the last Scalable Persistent Memory backup are stored on the drives.
The logical NVDIMMs can be restored from the drives after the motherboard is replaced.
