You have failed me for the last time, Time Machine!
I recently purchased a Synology DS420j RAID chassis.
The TL;DR is that this beast is a 4-bay RAID chassis loaded to the hilt with tools to make building redundant disk arrays a snap.
The first thing I did was point my MacBook Pro as well as the Mrs.’s newly purchased M1 Macbook Air. Time Machine backups at the shiny new memory-alpha NAS.
(Yes, I assigned it the hostname of memory-alpha. Welcome to Geekland).
