In this case constant mirroring provides instant fallback operation should 2 drives in one enclosure fail. I couldn't possibly consider that either senseless or dangerous. Perhaps I did not make it clear that this is TWO NAS enclosures and that the mirroring provides a CONSTANT backup. Unlike most Linux-based home-office NAS the Synology also support Recycle Bin on a folder by folder basis and there is also a setting that can restrict Recycle Bin access to administrators only. ------------------------------------------------------------------------ banned for life's Profile: http://forums.slimdevices.com/member.php?userid=56269 View this thread: http://forums.slimdevices.com/showthread.php?t=100561 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
