So I am setting up a zvol on my pool to act as Time Machine storage for a number of network clients. I'm using the second method described at https://openzfsonosx.org/wiki/Time_Machine_Backups, with one possible exception: it turns out I can format the zvol as either HFS+ or APFS—either one will work as a networked TM target—and I don't know how to choose. Does anyone have insight into this question?
Thanks in advance,
Dave
