The signature of this issue appears to be the ndmp_tar_writer() ERROR :

> 2015-07-28T10:53:15+0000 [74] *** E R R O R *** [ndmp_tar_writer:117]:Writing buffer 0, pos: 0

... and yet the log suggests that some NDMP 'processing' has been done :

> 2015-07-28T10:57:20+0000 [74] BYTES_TOTAL: 1648640
> 2015-07-28T10:57:53+0000 [74] BYTES_TOTAL: 1648640
