Iam comparing 2 filesystem using the below command.


rsync -navrz --exclude=logs/* /opt/otm/ glrrd@105.78.7.100:/opt/otm/


The output showing the files which are same in size and timestamp that are to be sync.

Iam using rsync 2.6.3 version so i dont have itemize changes option to debug the problem.

Is there anyway i can find the how rsync is finding the difference between the 2 filesytem

Ex: filesystem1

When iam running the rsync from filesytem1 it is showing to sync all the file in filesystem1 to filesystem2 when both the files looks same in size and timestamp

I don't understand whatmeans.

wsdl4j-bin-1.4.zip probably already existed on filesystem2, and you are not passing any of the --delete options to rsync, so I don't see any unexpected behavior here.

delete will delete files that don't exist on the sending side.

Suppose if the same file is present in both the filesystems then it should not copy the same file to the receiving file system.


File which are same in size and timestamp.

Don't use -v as option, it will list all files. Without it you will get a list of intended changes in the dry run.

Nevertheless you could compile a more recent rsync from scratch and put it in your ~/local/rsync-3.0.7 or similar.
