Hi I'm trying to understand this sort of stuff: https://lists.samba.org/archive/samba/2012-August/168907.html so. . . I setup DC1 with this /etc/rsyncd.conf: [sysvol] uid = 0 gid = 3000000 read only = no path = /usr/local/samba/var/locks/sysvol On DC2, I cron this: rsync -AXauzv rsync://DC1/sysvol /usr/local/var/locks/sysvol Test: kill samba on DC1. Result: the gpo's still work. That's it isn't it? I now plan to make DC2 a rsync server too and cron that back DC1. Surely it's not as simple as that. Is it? Cheers, Steve
