Thanks Andrew,
I am testing the rsync command using crontab and let it run on 4 AM in the morning since last friday.
I check and compare the moodledata, the size are different today. The source moodledata size is only about 8 GB, but the target size is about 14GB. Could you advise what happen? How come the size is different?
I am using: rsync -azvr.
Thanks and Regards,
Yulstar
