Please forgive my ignorance, I have searched for an answer but have so far come up blank.
Here's what I want to do:
Use rsync to backup from the fileserver (Ubuntu Server 14.04) to a NAS device. When this backup is complete then run rsync again to a remote server via SSH.
I have a nagging feeling that this won't work properly - something to do with how rsync marks files as already backed up and not changed since last backup.
Am I right to be suspect that this might cause a problem?
