My backup server from 2010 died so I had to buy a new one.

I want to use this machine as a backup server and a server for my private services. I have 3 disk of 4TB in a raidz ZFS pool, 8TB is available and one disk can fail and I have an M2 SSD for the server part of the machine.

I choose the mini-ITX format because the Intel NUC size computer have laptop component which are not reliable under heavy load and it is smaller than ATX desktop computer.

Here is the components:

* Intel Core i7-10700F Processor (16M cache, 2.9Ghz up to 4.8Ghz) 8 cores/16 hw threads 14nm

* ASUS ROG Strix B460-I Gaming motherboard Max 64GB RAM

* Corsair Vengeance LPX Black 32GB RAM (2x16GB, DDR4)
* Fractal Design Node 304 box

* Corsair RM650 650W power supply
* 4x Seagate Barracuda 4TB 2.5inch 5400rpm 128Mb SATA disks
* 500GB M2 nvme Samsung SSD

I use only 3 Seagate disks so I have a spare in case one disk fails.

I also connected to it the external disks (1.5TB and 2TB Western Digital) from my previous backup server.

I installed Debian Bullseye with ZFS on root and I expect this setup to be stable.

* If a disk fails, I replace the non working disk with the spare disk.
* If the power supply fails, I replace it with a new one
* If the motherboard fails, I put the disks in another computer
* If the computer fails and the disks also fail, only backup data is lost
