Ok, so the file retention and job retention parameters in client configuration does not block volume retention but just the catalog ? If i add autoprune=yes in client configuration, job and files retentions block the volume retention ? Ok, so if i have 10 computers (laptops and desktop) and many laptop are absent for long time, its better to remove volume retention parameter or select it with a high value ? -- You received this message because you are subscribed to the Google Groups "bareos-users" group.
