I have a strange issue and I am not sure which side it may be on. Setting up the tm share as described in the docs (doesn’t matter if dedicated user/share or auto dataset creation). TM starts to create a sparsebundle (something xxx.incomplete) and fails at the end in the process of renaming. 2025-1…

I’m having the exact same problem. Have you found a solution yet?

https:// discussions.apple .com/thread/256137390?sortBy=rank This solved it for me. When you make a timemachine copy a disk image is created. The name of this image can contain special characters like äó and this is currently broken on osx. You have to make a copy, let it fail, acces the SMB share…

The actual disk image had special characters? mine is named “mini.incomplete” to be renamed to “mini.sparsebundle”, so I wonder where the special characters may be?

I’m having also exact same problem. Trying to setup Time Machine backup from existing mac to a new Truenas server (version 25.10.0.1) but it fails on renaming from xxxx.incomplete to xxxxx.sparsebundle. Don’t see any special characters as well. Have you found any solution yet @thinkberg ?

No, it looks like it’s broken at the moment. In this post it points to a general issue: [image] New user cannot use Time Machine TrueNAS General Hi, I’ve TrueNAS 25.10.0.1 on my NAS and existing users are working fine, the first connected created a data set a…

I reported this on Jira, another of the countless bugs in Goldeye :frowning: Jira

It seems that the TrueNAS people “cannot reproduce” this issue but I can clearly reproduce it. Has anyone else had any luck fixing this issue? Or working around it to restore the Time Machine backup functionality? It works well on a system that I upgraded to the latest version, but not a freshly cr…

It’s pretty disappointing, as the answer is it will work in 25.10.0.1 while the ticket clearly states, it is affecting 25.10.0.1.

I have basically reopened the issue: Jira I just had it again set up and created the share and tried it. To no avail.

I managed to work around this issue by using rsync between the old host and the new one. Then, Time Machine worked without a problem and I could back up to the new machine just fine.

TM share setup not working - should I wait?
