Smart Sync or Binary Diff Tool
Posted on 2010-09-01
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.
