My current Time Machine Backup on my NAS drive, does not complete anymore after upgrading to 10.14 from 10.12. It starts successfully, but after sending 9GB of 52 GB to the NAS it stops. The Timemachine Backup on the NAS is ejected before the backup stops and I don’t know why.
Here some background information:
I made sure that the Macbook did not go to sleep during backup (Energy Settings, Tool KeepingYouAwake,…).
The NAS is mounted by SMB3 and the ssh connection is stable also after the Backup is ejected/not reachable anymore by Time Machine Backup process.
I checked the console warnings/errors:
I get a warning about low disk space and a few minutes later the connection to the sparsebundle backup is closed. But I don’t know which device is the problem. On my Macbook I have more than 20 GB available and on the NAS there is more than 1.4 TB available
I tried to check the size of the TimeMachine.sparsebundle on the NAS. I also tried to resize the backup to the max space of the NAS 2.9 TB. But I am not sure if that worked, I don’t understand the output:
