During the months (roughly a year) that I used Arq for backups, I grew weary of its complex interface. Functionally speaking, it works great; no complaints there. But its UI lacks the simplicity I longed for after using Time Machine for so many years prior. So I went back to Time Machine.
This time I didn’t try to use a NAS drive as a central data repository. I just bought an external hard drive for each of my computers and used those for backups. That eliminated the TM problem that motivated me to find a TM replacement, and it restored the data accessibility I always enjoyed in TM.
