It depends what you mean by "interrupted". There are 3 links to consider (dir<->fd, dir<->sd, fd<->sd) and any one of them could have broken. The scenario I'm thinking of is dir & sd local and fd remote so there are only two of the links to consider but it's not necessarily a simple problem.

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2d-c2 _______________________________________________ Bacula-devel mailing list Bacula-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-devel
