'Credentials not specified' error, but only for empty folders... So this is definitely an ongoing issue and it happened again today.
In this case, the folder was:
C:\Users\UserName\AppData\Local\SourceServer\8569009a4bc56cb306676939718ced68f7a8a78f96079249e53de77e527951c6
Again, adding an empty file worked around the issue.
Interestingly, another, virtually identical empty folder backed up without issue:
C:\Users\UserName\AppData\Local\SourceServer\60afa13063e0486041e632ed702bf4d5e2730d5054962f7c48eda99ddb006b51
Neither folder existed in the backup destination prior to running the failing backup.
Running the latest build:
8.0.4.5
This is definitely a bug of some kind
@Alexander Negrash.
I can re-create the issue.
