Unassigned Time Machine

GOAL

Setup UNRAID 6.6.6 for macOS 10.14 Time Machine backup over SMB to a dedicated Unassigned Devices disk that is not part of the array

 

There have been some reports of difficulties enabling Time Machine backups:

SETUP DISK

Main > Unassigned Devices

Format as xfs

Mounted as /dev/disks/Timecapsule

 

Settings > Unassigned Devices

Enable SMB sharing as desired

 

SSH to server

cp /etc/samba/unassigned-shares/Timecapsule.conf /dev/disks/Timecapsule/Timecapsule.conf

nano /dev/disks/Timecapsule/Timecapsule.conf

Add the following to the end of the file

vfs objects = catia fruit streams_xattr
fruit:time machine = yes
fruit:model = MacPro
fruit:advertise_fullsync = true
fruit:aapl = yes

 

Main > Unassigned Devices

Edit script for disk in Unassigned Devices

This will load our SMB configuration file and reload samba to enable these settings each time the disk is mounted regardless of auto or manual mount

#!/bin/bash
PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin
## Available variables:
# AVAIL      : available space
# USED       : used space
# SIZE       : partition size
# SERIAL     : disk serial number
# ACTION     : if mounting, ADD; if unmounting, UNMOUNT; if unmounted, REMOVE; if error, ERROR_MOUNT, ERROR_UNMOUNT
# MOUNTPOINT : where the partition is mounted
# FSTYPE     : partition filesystem
# LABEL      : partition label
# DEVICE     : partition device, e.g /dev/sda1
# OWNER      : "udev" if executed by UDEV, otherwise "user"

Unmount and mount disk again to get the disk correctly mounted as a Time Machine compatible share

 

MACOS 10.14 SETUP

Mount Timecapsule share via network

Open System Preferences > Time Machine

Select the newly available UNRAID share

I have selected encrypted backup as the disk is unencrypted xfs

Backup as desired

Very nice of you to do this. The sad part if that we need to do something like this at all. IMHO, someone should not do ever go into and mess with config files on a system like this, there should be an option just to turn on and off like other NAS devices have. It is not like this is "new" it has been around for a very long time yet unRaid seems to have such an issue with it. This would also require me to use another drive when I have put in a SSD as cache large enough to also be my TimeMachine drive. 

 

I really do thank you for taking the time to document this. I really just hate having to go in and mess with files not knowing if some other update will do something to such a file that would again require you to set it all up again. One could likely forgot about it having used it for X amount of time for it then to just stop and not remember that they made such changes to make it work.

What issue are you having?

 

IMO it’s fairly simple to setup via AFP. No more complicated than any other share.

 

LT has also announced that they are working on TimeMachine backups via SMB hopefully to be included in 6.7 so this procedure probably won’t be necessary.

@matryska Thanks for putting this guide together! I am excited to give this a go. One question, is there any way to limit how much space the time machine backup will take on the share with this method? Or will Time Machine just use all of the available space on the drive until it is full? Thanks for your time and help!

It appears that /dev/disks does not exist on my system, has something changed?

Not sure that has ever existed!    /dev/disk (without an ‘s’) does exist.    Perhaps you are thinking of /mnt/disks as is used by the Unassigned Devices plug-in?
