I should rephrase my question: shouldn't the whole system be backed up by battery for power outages?

The NVDIMM is powered by supercapacitors long enough for the DRAM contents to be copied to NAND flash. After the copy to NAND flash is completed, the NVDIMM no longer needs power and the original volatile DRAM contents are saved to the non-volatile NAND flash.

But the nvdimm still needs battery when there is no system power?

What do you think of using NVDIMMs for RAID storage backup? What applications do you think might be a good fit?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
