Hi Rick, thanks for reply^^

Yes it's exactelly what i want to do.

For exemple i do:

generate backupset node_name prefix_name devclass=DISK datatype=all retention=15

In this case the backupset was conserved for 15Days and after that he was 
delete.

Can i do a script to generate the backupset all 15 days ?

Regards, Mickael.
