Replication using NFS.

Hi all,


I am going to implement a script which will use NFS to replicate data between two SCO unix servers. It will take files with mtime -1 and copy the data periodically .In this regard my questions are :

Is this approach good and reliable enough with respect to loading servers, accuracy and redundancy.

Also is there any way to detect the changed file as it changes without using a long search with find's mtime, as this searches the whole bulk of data each time it seraches for modified files less than 1 day old. If I have 100gb of data (increasing with hours) , mtime command have more data each time to search and will become slow with time.


Thanks in advance,

Dexter

SHOWMOUNT(8)						    BSD System Manager's Manual 					      SHOWMOUNT(8)

NAME
showmount -- show remote NFS mounts on host SYNOPSIS
showmount [-Ae36] [-a | -d] [host] DESCRIPTION
showmount shows status information about the NFS server on host. By default it prints the names of all hosts that have NFS file systems mounted on the host. See NFS: Network File System Protocol Specification, RFC 1094, Appendix A, and NFS: Network File System Version 3 Protocol Specification, Appendix I, for a detailed description of the protocol. -A Search for NFS servers advertised via Bonjour. -a List all mount points in the form: host:dirpath -d List directory paths of mount points instead of hosts. -e Show the host's exports list. -3 Use mount protocol Version 3, compatible with NFS Version 3. -6 Use only IPv6 addresses to contact servers. SEE ALSO
mount(1), mountd(8), nfsd(8), mDNSResponder(8) BUGS
The mount daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless. showmount will only display the information as accurately as the mount daemon reports it. HISTORY
The showmount utility first appeared in 4.4BSD. 4th Berkeley Distribution September 26, 2010 4th Berkeley Distribution
