TEST RESULTS after applying the patch "Dynamic_hash.diff" with new rsync version 2.6.8. ------------------------------------------------------------------------------------------------------------------------------
The patch was installed on the source server and I tested with a 2 GB file transfer with following options and these are the timings... 1. No DESTINATION File - 2 GB - 12 min 2. With DESTINATION File nothing changed - 2 GB - 21 min 3. With DESTINATION File header information changed - 17 min The first 2 were tested with "rysnc -zv" and the last one with "rsync -zv --no-whole-file" So this shows that RSYNC performs faster when there is no datafile is present. For Oracle datafiles the diff algorithm doesn't work even with the patch. Literally it should have taken less than 12 min to just compare and update the header changes but it took more than 12 min when the file is already present at destination(target). I am not going to give up I am going to try again and see...
