macos time machine shared drive permissions issue
Desire:
- I have an external time machine backup drive, I'd like all my backups to be stored there through time machine.
- computerA (Monterey) - is using the drive as a time machine backup drive
- computerB (Monterey) - is attempting to use that external time machine backup drive on computerA
Issue:
- using system preferences > time machine > select disk > [select] hard drive > authenticated (with my admin account to the computer)
- error: "You do not have the necessary read, write, and append privileges on the selected network backup disk. Please connect as a different user or contact your network administrator"
Info:
- Back up to a shared folder with Time Machine on Mac – Apple Support (UK)
- using this article I was able to see the backup drive
- it gave the drive an option as a backup drive
- I even added my user account to the shared interface with read/write access.
- before macOS server was discontinued I was able to do this and still can on the macOS server now with Monterey.
- you could store all your backups on an external drive.
- looking at the permissions this drive I have "0 drwxrwxr-x 14 root admin 544 Sep 30 10:08 Backup"
- do I have to change the ownership of the hard drive to admin group to make this work?
- the backup folder on the drive does have "0 drwxrwx---+ 6 root admin 204 Apr 29 2022 Backups.backupdb"
- Permissions: I did notice
- 0 drwxrwxr-x@ 9 root wheel 288 Sep 30 09:10 Backup
- so clearly the user account was not in this wheel group
Question:
- How can I use the 1 external time machine backup drive with multiple computers?
