Hi, Unfortunately I have no solution for you but, if you find something, please share :-) PS : Did you had a look to compression algorithm ? Some perf issues have been solved by tuning this on our infrastructure Regards -- You received this message because you are subscribed to the Google Groups "bareos-users" group.
