Time Machine on macOs Sonoma

[eng]

Hi,

I have two macbooks. One has Ventura installed, on the other I have upgraded to Sonoma.
The settings for smb share (multi-user Time Machine) and backup datasets are identical.


The problem is that macOs Sonoma backup dataset has stopped creating automatic Snapshots.
In the dataset with Ventura everything works fine.

Auto snapshot is created when macOs disconnects smb share, right?

Does this mean that this is a bug on the macOs Sonoma side?

Has anyone else experienced this problem?

Version: TrueNAS-13.0-U5.3

After the backup is complete, sbm share disconnects correctly.

Yep, I'm getting this exact issue on TrueNAS-SCALE-22.12.4.1 and a 2021 MBP after upgrading to Sonoma. Last snapshot I have is from the last backup from Ventura. No snapshots created since then. Along with that, time machine has become quite flaky as to if it will even complete a backup successfully when in sleep. Since I changed nothing on the TrueNAS side, I'm guessing they broke something in Sonoma.

Hello, I have the same problem with truenas Macos Sonoma and the Timemachine.
I use TrueNAS-SCALE-22.12.4.2.

I have now noticed that the TimeMachine backups work when I create a dataset with quota. If I do not set a quota for the TimeMachine dataset then no backups work under somona. Is this normal?

Bumpity, bump, bump.

All Sonoma machines here, seeing same thing, although new to TrueNAS to no reference point before TrueNAS-13.0-U6.1.

Of interest, after a successful backup, the mount does seem to hang around.

The issue was logged in iXsystems' Jira instance (NAS-125197). Essentially, the fix came to Scale in 23.10.1, but won't come to Core until 13.1. I can confirm that the fix does indeed work, but tmprotect seems to only work with a multi-user time machine share/dataset and not a basic/single user so keep that in mind.
