It is usually because we failed to write data to the destination drive, maybe because you lose the privilege to write any data to this drive.
if you used a general internal drive as destination, please check and correct the writing privilege, or choose other drive as destination.
if you used an external drive as the destination, after check that the connection and the writing privilege is ok, you can re-make the seletion(sometimes, the drive volume for the external drive is changed).
If you used a network drive as destination, please make sure you have the privilege to write data, and you can try to map network drive: open a folder on your computer, then click "Tools"->"Map Network Drive...", then find your network drive by Browse... button beside Folder:, then check "Reconnect at logon", then click "Finish" button to save. Then choose the mapped drive as destination.(or if you already mapped the network drive, you could try to re-map it.)
