I r= un a file server with samba acting as a PDC. I also run a second server as a BDC.=A0 What I = would like is a method for keeping both servers "shared data" drives in sync when= both the PDC and BDC are running.=20 I am currently doing an incremental update twice daily to the BDC using rsy= nc over SSH.=A0 It works, but its just not good enough.. if the PDC goes down, anyt= hing created or altered after midnight or so, isnt propagated to the BDC.=20 I understand I can use ZFS to accomplish this easily.. but from what I've r= ead, you still need to manually push updates to the backup server over ssh via cron.=A0 So= I would still have windows of time where the file systems would not be in sync..=A0 am I = heading in the wrong direction here? I am beginning to think I am..=20 I've been afraid of NFS for some time.. remembering back to the days when i= t was just not safe to use NFS.=A0 I may have carried that fear on irrationally.. is N= FS a viable=20 solution to my problem these days?=A0=20 Thanks for the advice! +-+ AMARU =0A=0A=0A
