I experienced the same, also using finder works perfectly, only timemachine is experiencing these permission issues.

I did set it up as a tm share (also if I didn't I wouldn't be able to select it at all, would I). I did also select a floor, changed it two times in fact as I was debating how much space from my cache drive I wanted to give to tm backups as I already filled it once.

Sorry, was focussing on the Mac side of things. unraid-diagnostics-20251219-1252.zip

I did switch to the tm container which works without issue, as such I don't have unraid configured as a target anymore. But I was getting the exact same error as op, I’ll see if I can recover the logs from this morning. See attached logs. Yes, I did check the permissions, users and everything over and over again, it stopped working a while ago when I removed the tm completely on my old Mac and deleted the share. When I went to set it up, it never worked again. 2025-12-19 10:07:43 Creating an encrypted sparsebundle diskimage at /Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete 2025-12-19 10:07:43 Using a band size of 128 MB (on a volume with size of 524,29 GB) 2025-12-19 10:07:45 attrVolumeWithMountPoint 'file:///Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/' failed, error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied" 2025-12-19 10:07:46 Limiting logging for limit: aFewTimes key: "map auto_home" 2025-12-19 10:07:46 attrVolumeWithMountPoint 'file:///Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/' failed, error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied" 2025-12-19 10:07:46 attrVolumeWithMountPoint 'file:///Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/' failed, error: Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied" 2025-12-19 10:07:46 Mountpoint '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine' is still valid 2025-12-19 10:07:47 Attached as disk4 to '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete' using mode 'read/write' 2025-12-19 10:07:47 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:48 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:49 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:50 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:51 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:52 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:53 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:54 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:55 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:56 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:57 Failed to find Time Machine volume on '/Volumes/.timemachine/10.0.0.10/2A49F348-862C-4D88-8B41-60258C29359C/timemachine/MacBook Air di Loris 2025-12-19-100743.incomplete', found: 2025-12-19 10:07:57 Backup volume device entry did not appear in IOKit registry in a timely manner!
