Hi,
I am trying to set up time machine TM on my MacBook Pro MBP to backup to an external hdd that is connected to my Mac mini. In system preference, I have set up share of the hdd and added a user profile that has read+write privileges.
When I set up TM on my MBP using that user profile, it gets an error message saying that it doesn’t have necessary privileges to access the disk.
what am I doing wrong? TIA, Rod.
MacBook Pro 13″, macOS 10.15
One more step:
provided you are running at least 10.13 High Sierra on the Mini (the computer holding the shared drive) you select the shared folder or drive in File Sharing, and hold down the Control key while you click on its name, then choose "Share as a Time Machine backup destination":
Back up to a shared folder with Time Machine on Mac - Apple Support
Once you do this, the folder/drive will be made available as a time machine destination, an extreme special case, and all should proceed normally.

Thanks for your reply, have chatted with Apple support ( very helpful ) and come to the conclusion that it is not possible to use a hdd, that is already used to back up a Mac with TM, to backup another Mac using TM. Just need to buy another hdd.
You might be able to create a separate Folder on the backup drive and share that Folder as a time machine destination.
Backups do tend to get big -- recommended size is more than 2.5 times the size of the stuff to be backed up.
Grant access to ext hdd to another mac
