I like to use ZFS raidz2 at a minimum. More or less bulletproof from a storage/hardware standpoint.

The system I referenced currently has x8 4TB NVMe drives on ZFS raidz2 and x8 16TB rust drives also on raidz2. I use sanoid to snapshot like crazy (down to 15 minutes) and then syncoid to push snapshots and then some to the spinners ZFS array. Plus zfs send remote to offsite.

Modern switching power supplies are incredibly reliable. Then do proper “half load” dual power supplies from dual conditioned power feeds with UPS and generator. Losing power to a machine almost implies an extinction level event or complete incompetence on the part of a data center operator.
