I have a system with 12T usage, CentOS 6, raid6, xfs, email system
I need to rsync the data to standby server, now it takes around 6 hours to finish the task
I found that the volume of really copied file is not too much, around 100k files, but the latency seems to scanning the changes of folders
What can I do to improve the performance of rsync? Target is within 15 minutes, is it possible?
