File Replication

By cpfeiffe ·
Hello.

I need to find a freeware file replication tool (GUI and/or Web based) that fits the following requirements:

1) Replicate files from a Unix and a Windows NT server to a Windows NT client based on modify time (no need to overwrite the files that haven't changed).

2) Run via a scheduled time and provide the ability to run this at command or run in real-time.

3) Be able to replicate an entire folder or selected files as needed

4) Delete files that are on the client and no longer exist on the server.

I have thought about a simple script that will clear all client files and then push the files from the server with ftp but we don't always want to kick users out of files that aren't in need of replication so we need something more manageable.

I'll appreciate the suggestions.

Have a look at rsync. It's free and might do what you want.

This tool appears to only work on Unix systems.

I use the UNIX command 'rdist' for replicating from to Windows NT and other UNIX servers. rdist is available in AIX and HPUX. I'am sure if other brand of UNIX is available, but this command worked perfectly.

I forgot to mention, you need to config something like NFS to mount as a filesystem in the UNIX server or vice versa.

rdist appears to only push files and doesn't perform comparisons. I also need to push from NT to NT and not just Unix to NT.

The rdist command will do simple comparsion. They will compare the file size and the time stamps of each file. If either one of this attribute was changed, the dest. files will be updated. If the original file removed, the destination would also be remove. Actually, I am set up like this in my office for sync. the web page from UNIX to UNIX and UNIX to NT. It work perfectly.
If you want to replic. NT to NT. I temp. suggest you use NFS mounting both NT dir. to the same UNIX server and use rdistcommand to replic to itself. I know it is not the best answer, but at least this will work.

I have other tools also that will work if I can mount the file systems via NFS. The problem is one machine is internal and one machine is on our DMZ. We can't use NFS for security reasons. We need a tool that will open a session, do the job, and exit the session. I've told Security that we can automate a procedure that will mount the NFS, run the job and dismount, but they aren't too happy with that idea. We may be able to get this to work by mounting the internal NT to the internal Unix and running rdist from the internal Unix to the DMZ.
