TimeMachine with samba on an Ubuntu server

Marinus Klasen

The other day I setup an Ubuntu 20.04 server that runs a couple of docker containers. Since the machine is equipped with a 1TB hard disk I also wanted to use it as a TimeMachine backup location.

Finding the right configuration took me a while, but with the settings below the disk automatically showed in the TimeMachine settings.

/etc/samba/smb.conf

[global]
    min protocol = SMB2
    vfs objects = fruit
    fruit:metadata = stream
    fruit:model = MacSamba
    fruit:posix_rename = yes
    fruit:veto_appledouble = no
    fruit:wipe_intentionally_left_blank_rfork = yes
    fruit:delete_empty_adfiles = yes
    fruit:aapl = yes
    fruit:time machine = yes
    server min protocol = SMB2
    log file = /var/log/samba/%m
    log level = 1
[TimeMachine]
    comment = TimeMachine
    guest only = Yes
    path = /home/yourusername/timemachine
    force user = yourusername
    writeable = yes

    Thanks for sharing this.

    I was wondering if this is still working for you as I am finding I get an error “ The backup disk image could not be created.”

    I’m on Catalina using a ZFS server on Ubuntu.

      Hi Jeff – I haven’t had any issues with it so far. I’ll double check the status and config next Monday. 🙂
      Feel free to reach out per mail/Twitter, happy to help.

      Yup – the config is still the same and backups are running.

    Hi,
    is there something else I need to install to make it run? In the past Avahi was needed, too.

    Thanks for your help
    Jürgen

      I don’t remember installing anything else, but as Jeff also had some issues, there might be something missing in the config. What’s the issue your having?
