rsync is good so I think the problem is elsewhere. Some ideas to help diagnose the problem. One easy way to test if rsync is doing the job is to do sha256sum -b * >sha256sum.txt This should create a file containing all the checksums of the files in the current directory. You then rsync all the files to the remote server. You then do on the destination server. sha256sum -c This will check with a high level of certainty that the file both local and remote are identical. When you do the rsync from the database, I would not compress the backup of the database. This will let rsync send less data after the first initial transfer.
