I will use a shared network drive for TimeMachine backup. I can mount the drive via the Finder: Network -> MachineA -> Drive0
. Get Info shows the drive is mounted as: afp://MachineA._afpovertcp._tcp.local/Drive0
. This is the same way a second drive (call it Drive1
) is mounted from a second mac server (call it MachineB
). When I attempt to select Drive0
as the TimeMachine disk, it is not listed as an option, but Drive1
is! Incidentally, MachineA
is currently using Drive0
as a TimeMachine backup disk. Call the client (to-be-backed-up) computer, MachineC
.
What is required of a drive from a networking perspective for it to be listed as an option when "Select Backup Disk" is invoked? In other words, what do I need to check/ensure about the connection between MachineC
and MachineA
such that Drive0
is mounted/discovered in such a way that it will be listed as an option for selection in the TimeMachine preference pane?
(MachineA
, 10.11; MachineB
, 10.13; MachineC
, 10.12)

The problem results from this detail:
MachineA
is currently usingDrive0
as a TimeMachine backup disk.Thus,
Disk0
was being shared as read only and hence the problem.Looks like there is a fix for this in 10.13, a location can be shared as a TimeMachine backup destination:
