[ FROM < backup_device > [,...n] ]
[ WITH
[ RESTRICTED_USER ]
[ [,] FILE= {file_number |@.file_number} ]
[ [,] PASSWORD ={password|@.password_variable} ]
[ [,] MEDIANAME ={media_name|@.media_name_variable} ]
[ [,] MEDIAPASSWORD ={mediapassword|@.mediapassword_variable} ]
[ [,] MOVE'logical_file_name' TO'operating_system_file_name']
[,...n]
