As its not directly Veeam problem the case is going to be closed but I hope that maybe there should be options for retrying if there is some error reading file. I had another case where one tape job terminated with error - Failed to open file <file name>] for reading. Unable to read file block.
And entire tape job was terminated. Is there possibilty to create options to configure number of retries for example. If there is some temporary network error and file can' t be read then tape job tries N times and if there is still error then logs error and file name and goes to next file and tries to continue. And it does not terminate entire job with first error which may not be even fatal.
