to me it reads like its blaming the truenas destination, but the truenas reports no problems. and the file app_10da5.... is 9Gb and created on the 24th May. Should I just delete the files in the snapshot folder and let it re-create them ?

Oh, dolphin also complains about the file not existing, when I try to open or delte it, so I gues its just corrupt. /case closed.

Hello @aartjansen
Glad you could figure it out on your own.

[scooke]

What happened and what was the solution?

[AartJansen]

Not sure exactly the cause, however the app being backed up was peertube, and a update was scheduled and failed around the same time. The fix was deleting the corrupt file in the snapshot folder on my truenas from shell. Then re-running the backup
