An alternative to RAID1 on 2 * 4TB. ![:idea:]( "Idea")
PCIe NVMe adaptor with 4 TB. Big spinning rust disk on USB 3. You use the 4 TB SSD 24/7. Backintime or equivalent backup to the lump of iron. You can then recover to the day or hour or whatever your backup is set to. Some will backup every file the instant a file is closed.
I use an adaptor plate that fits under the Pi so there is nothing blocking the cool air to the heatsink or access to the GPIO pins. The plate faces the SSD down so there is cool air to the SSD. Runs a good brand of SSD at PCIe 3 with no problems. The SSD is one rated half way down the list from fast to lowest power usage.
The magnetic monster will be sloowwww if SMR and fast enough if CMR. SMR is ok for logging and for an overnight backup but pathetic for lots of little updates from a continuous backup program. Choose SSD for continuous backups.
