Re: [Bacula-users] minimum volume retention period

Hi Folks,

I've read this thread, and I'd want to get some clarification about this topic.

if Julien have set the Volume Retention of incremental in 35 days, I don't understand why "(around 15 june Incr-0001 should be recycled)".

2) is it correct that on 1 july Full-0001 it's recycled? if Volume Retention of Backuo Job was set as of 45 days. On 1 June, Full-0001 it's changes it's status, it will be recycled on 15 july aprox. Pleae correct me if I'm wrong.

Thanks in advance!
