Using the option " rsync -zv --no-whole-file --stats" it took 1:15 min and using "rsync -cvz" options earlier had took 1:25 min so there wasn't much time savings I thought it would be a big difference since the files are there and only little is modified (header info) + additional datafiles. {{ Other info is I am running "rsync version 2.6.5 protocol version 29" on source and "rsync version 2.5.2 protocol version 26" on destination server }} Also one more thing from the stats rsync has transferred few files more than once "Number of files transferred: 2" Why is this so ? Number of files: 1 Number of files transferred: 2 Total file size: 167780352 bytes Total transferred file size: 335560704 bytes Literal data: 67010560 bytes Matched data: 268550144 bytes File list size: 42 File list generation time: 0.001 seconds File list transfer time: 0.000 seconds Total bytes sent: 184089 Total bytes received: 254026 sent 184089 bytes received 254026 bytes 2131.95 bytes/sec total size is 167780352 speedup is 382.96 Thanks, lsk. -- View this message in context: http://www.nabble.com/Rsync-help-needed...-t1170765.html#a3164850 Sent from the Samba - rsync forum at Nabble.com. -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
