I *really* think I'll be collecting iptables data...

Nothing else than ssh-tunnelled BackupPC dumps.

Indeed I'm using XferLogLevel = 2
Skip actually only appears in "Incr" XFerLogs, which it seems then to be
substituted by "same" in "Full" backups...

I actually put XferLogLevel back to 1, let's see what will happen...

Will read about it in the BackupPC Documentation

OK, still a bit confused... Will eventually come back on this issue
later on...
