Hello Himanshu
Thank you for your answer, yes we get the copy_id at the end of the info of this command, but when I try to clone I get an error
regarding the backup on the secondary :
[ERROR] SMO-13032: Cannot perform operation: Clone Create. Root cause: SMO-03040: Backup copy 123366 does not exist on secondary storage. Valid backup copies are [].
or the copy exist on secondary, and it is seen from the graphical SMO, and from system manager, I get the same error from SMO gui :

If someone succeed in cloning from secondary...thank you for your help.
best regards
Noel
