Rsync and remote IP problem
Hi, I hope you guys can help. CONTEXT: I have a readynas 2120 Ultra 2 at home, and a Qnap at work. The Qnap is on our network at work, and in windows explorer where is shows the network it has t...
If you have a corporate firewall in place, you may not be able to do this at all without modifying its rules. Though it will likely be easier if you "push" the backup from the qnap.
In the push scenario you need a dynamic dns name for your home router, and you would need to forward the rsync port from your home router to the ultra. If you are using rsync over ssh, that is (I believe) port 22. Regular rsync is port 873. The rsync log on (username, password) would need to be set to something that allows access to the ultra share. (You'd also have to configure rsync access for the ultra's share, and install the ultra's public key on the qnap).
The ultra's ftp server will also accept secure ftps connections (using "explicit tls"), so that is another protocol you could try. If the qnap has an incremental ftp backup mode, then ftp might be the way to go. Opening port 22 to the NAS does create some security risks (and might be blocked by your corporate firewall or your ISP). Another benefit of FTPS is that you can test the connection from a Windows or Apple machine fairly readily, using an FTP client like FileZilla.
Also, getting the initial backup done will be much faster if you bring the ultra-2 to your office.
An alternative to all of this is to use cloud backup (CrashPlan, Readynas Vault, Egynte, etc).
