file truncated (expected xxxx bytes, got 0)

"Error for USERNAME filename.ext': file truncated (expected xxxx bytes, got 0)"

This issues usually occurs while backing up UNC paths from a NAS device such as a TureNAS, Synology, Qnap etc.

This error indicates that the backup application was expecting a file size of xxxx bytes for the file 'filename.ext', but it only found a file size of 0 bytes. This error could occur if the file is missing or if there was an interruption during the backup process that caused the file to be truncated.

To resolve this error, you should check if the original file exists and try to backup the file again. You may also need to check the backup settings and ensure that there are no network interruptions on your LAN during the backup process.
