Smart Sync or Binary Diff Tool

We have the need to transfer copies of our builds to India for testing. These builds are about 4G in total but have huge amounts which do not change between files.
So the build contains a combination of many files and big CABs (or equivalents) . Some of the binaries might only change by a few bytes for the version stamping.

=> Is there a copy or sync tool out there which is really smart and can build remotely (either directly or by a copy and process) a copy of a file area based on a "seed" area. This seed area on the remote site would simply be a copy of the previous build ? It would need to recognise the common parts in the binary files.
Context : Windows Server 2003 / 2008

Is this essentially Microsofts DFS Replication ?

Now a normal sync tool would be file for the stand alone files that don;t change but hopeless for a very large binary which only has say 2% of the file changed. It would have no choice but to copy the large binary file.

Thanks

Hi,

Have you looked a rsync?

Or for windows:

Most international development team use some Repository tool ( like "SubVersioN" ) that allows :
-any "client" to replicate locally all (or a branch) of it (using CheckIn/CheckOut methods to avoid data write conflicts)
-versioning all files in the Repository
-a global Repository backup

You may although use a replication system like DFS to synchronize a directory in 2(+) locations but it requires sharing some Domain info

If your build does change all files at every new build, both Win2008 R2 DFS and SVN should allow for a differential/incremental evaluation...that is to be tested anyway

SVN (SubVersioN)

On Windows, I have been using http://www.visualsvn.com/server (and its VisualSVN client) with success

Thanks. i looked at rsync but could not run. No csyxxx.dll (some library dll to convert between windows to linux)

We use TFS 2080 for our source control and subversion is more of a source control tool than a replication tool.

Normal "sync" tools result in the 4G build needing 2G of b/w to copy. I am hoping that a block level trial will reduce this dramatically. Was trialing R1Soft but can't get the s/w to work. This has block level copy feature.

My suggestion is to try using SVN (a source control tool) to replicate a directory locally:
-costless
-should allow for some incremental updates (Unsure with your binaries)

Got rsync working using the url within the url for cwRsync but haven't got all the options right as i end up with the same sync transfer count as other tools (even using --inplace). Suspect issue with file times being used insead of CRC of file content.

As builds have complete binaries and files, exe, pdb, dlls , cab files etc i can't see how the SVN solution will help but thats for contrinuting.
