(I was answering to the previous comment wondering if ramdisks still have any interesting usage nowadays.)

About 150 TBW endurance on a 250 GB Samsung M.2 NVMe Evo 970+. On paper that is, but since it is the OS SSD with Windows Server 2022 STD (sole DC AD/DHCP/DNS/Hyper-V), in production, I won't take any risk. RAID 1 in this scenario would have changed nothing. On the side, I have 40 TB RAID10 for storage.

So I cancelled the first C2 exec (with C2 encrypt on) when I reached 195 TBW on the SSD. Monitoring the ramdisk use still shows about 3:4 ratio on complete snapshot.

I have about 1 million files on the 2,29 TB data to backup.

I had indeed the RAM sticks available for free, simply had to take them (2x16 GB ) from a decomissioned ML350 Gen9 (which uses DDR4-2133P ECC Reg). It now serves me as a bench, litterally.
