I have a MSP360 Standalone Backup client which is backing up to an SMB share on the local network.
This configuration works perfectly for the multiple other clients I have running on the network, backing up to the same location, and did in fact work for this client once in the past week (after a full OS reinstall).

I am able to access (and write to) the destination SMB share using Windows explorer on the client.
The destination computer shows the client login as successful.
The MSP360 backup configuration confirms the credentials I had entered for the local storage location as correct and working.

However, when I attempt to run a backup, I receive the following error:

Network resource cannot be accessed (Code: 1514)
Credentials for the following network resource(s) are not specified: \\server\share\folder\

I even went so far as to completely delete the '%ProgramData%\CloudberryLab' folder, and reconfigure the backup entirely from scratch, with the same result.

I am using the 'Legacy' backup type, in 'simple' mode.

However, I noticed during my testing that the backup was reporting that it was failing on empty folders. Deleting the folder in question simply caused the backup to fail on a different empty folder.

Unselecting the 'backup empty folders' option allowed a full backup to complete successfully.

I can't see anything special about these failed empty folders and it doesn't seem to fail on ALL empty folders, just some of them.

Based on the results of my testing, I suspect that the error I'm getting is not accurate.

Not sure where to go from here!
