mention rsync is the one that I'm considering. I knew in Linux world but I've RSYNC along the way coz I've implemented
SAMBA in our network.
Thanks again,

However know that if you're running databases, you may want to consider mirroring at that level. We don't mirror in "real time", but have considered the fixed intervals to be "good enough". rsync is an amazing tool in that it only copies the differences between two files over the wire. The problem is, it's also very CPU intensive when calculating the checksums. Another alternative someone mentioned to me once is that you could setup a Software RAID-1, connecting to the remote disk over iscsi and have the RAID-1 perform lazy writes to the remote disk. Never tried that type of implementation, but it might work. Or... you could use a NAS device where both machines share the same data (or two nas's which do mirroring at the block level) and leave Linux out of the picture. Granted this is a pricey (read $$$$ to $$$$$) solution. -Rick -- Rick Johnson, RHCE - [EMAIL PROTECTED] Linux/WAN Administrator - Medata, Inc.
