This utility makes an exact replica of files on a machine
via the network to another machine. It was designed for load-sharing
situations where all the servers need to have a copy of all the files,
but can also be used for other situations, for example to publish files
from a development machine to a production machine, or to have a backup
server standing by that can immediately take over without first having
to restore from a backup.
The utility uses it's own protocol on TCP/IP port 9577 and is totally
independent, you don't need things like an FTP server or Microsoft
Networking (disk sharing). Traffic is one-way only, files are only sent from the
master to the slave. The program uses passwords (challenge/response) to
protect the access and an MD5 hash to make sure the files on the slave
are exactly the same as on the master.
There are two components, a "SyncUpload" program that runs
on the master (for example once per day), and a "SyncServer" program
that runs continuously in the background on the slave. The SyncUpload
program contacts the slave, asks which files it has, sends new and changed
files, and sends instructions to delete old files. The result is an exact
copy on the slave of all the files, even the date/time is the same.
