Synchonizing data files and creating a NAS third data set

I am posting this in a linux forum, although it could be in networking (or another), because of the need for linux familiarity which is not as likely to be present in a networking forum.

Some time ago, I copied all the files from my Windoze computer over to a second hdd on my Ubunutu 8.04 machine and have been updating the folders with new docs, files, etc. I forgot to inform my wife who is linked to my old WXP computer and she has been happily updating those files. Now two sets of files.

So I now need to synchonize the two different sets of file into one and want to put that onto a NAS hdd on my network so that we are both accessing the same set of files in future.

I think one can do that with XCopy in Windows if you know the "start date" (i.e., the date I had copied the files over to my Ubunutu computer. But I don't know how to find that date, and once found how to issue the XCopy command in windows.

Also how would one duplicate that in Linux?

There may well be package software that will do this through a GUI

Hope I'm not too confused here. Anyone see a practical overall plan for this? TIA

Great looking program! And VERY pricey!

Thanks, but I'm thinking a much simpler one-time solution which results in a single new set of files on an NAS hdd. Once that set is created, the problem of synchronization is over.

Sorry for the oversight over prising.

For your requirement btw windows/linux a solution of using FTP could work, you can make either windows machine or linux a linux server and if not even SSH with SFTP also a good choice.
For client application you can use Filezilla which is freeware and have many facilities.

But because of the limitations of FTP, FileZilla can only look at two things: file size and file date. Date is preferred, but you must enable Preserve timestamps from the Transfer menu. You can then transfer the files once to make sure the times are correct. Now you can enable directory comparison on the View menu.

Other clients support non-RFC compliant extensions like XCRC, XMD5, and XSHA which can hash files to see if they're identical and such clients can do true directory synchronization. However, it's not RFC compliant and so will not be implemented into FileZilla.

For them you still will need some FTP Client/Server solution from some proprietary vendor

Hope this heps this time

One more solution to fulfill NAS needs could be by making some linux system space as your storage with filesystems either ext3 or GFS and further can be exported via NFS and from windows side you can use SFU(Service For Unix) client for using that NFS share as a maped drive in windows.

Easy to setup, multi-platform, FREE, completely configurable, automated synchronsation, ...

Check it out. Might be what you need! I'm using it in an AIX/Windows/Linux environment without any problems.


Kind regards,
