@mike_k If you want some cheap backup solution and don't need peak IOPS, consider some cheap thin client and some cheap SATA-HDDs or even SSDs with USB Adaptor+Case...
May look messy but you can get a decent mini server for backups for less than the MSRP of a @Raspberry_Pi #Pi4B8GB or #Pi400...
Not to mention that most #ThinClient|s are #fanless and #LowPower, reducing the costs even further even if you don't have to pay €0,62/kWh for electricity.
