Oracle : Ошибка ORA-19585

"premature end of volume on piece %s"
*Cause: While creating the indicated backup piece, an end-of-volume
condition was encountered before all of the backup set control
data was written to the backup piece. This is most likely a media
error, because the amount of backup set control data is very small
in relation to the total amount of data in a backup set.
*Action: Retry the piece with a larger piece of output media.
