ROCK Backup fails (System.IO.IOException: Input/output error)

[pwo (Peter W. Osel)]

Hello Community,

my roon ROCK backups are failing:

Roon 1.8 (Build 884) (ROCK) on an Intel NUC10 backup fails with the following messages in RoonServer_log.txt:

The CIFS share resides on a Mac mini running macOS 12.1

The directory RoonBackups gets created with a few files in it:

Any idea how to further debug the backup failure?

Kindest regards

The only person who can write out to that directory is the user xxx. If that is a valid user, cool.
It is also the second crash report including sooloos I’ve read today.
Was something just pushed out?

[pwo (Peter W. Osel)]

User xxx can write and create files (all the files and directories shown were created by the backup). The backup failed a couple of weeks ago, just did not have time to ask for help earlier.
