Backup Remote to FreeNas Server

Hello,
I am new with web hosting and Centos web panel.What I want to do is use my FreeNas server to back up my centos web panel servers...
Has anyone ever did this. Is so could you guide me in to what steps to take to get this to happen...

When it comes to the Access-Key: im lost...

I would like to start backing up the server remote..

Thanks...

Also Can I backup more than one server with the same User...

How will that work with 2 different Access keys?


I get up to here and I cant find this file..

Don't forget to add pub key from file /root/.ssh/backup/id_rsa.pub on the remote server to the file "~/.ssh/authorized_keys"

Ok So heres my update... I can connect to the remote server with a terminal connection from the CWP. But when I use the test connection in Manage Backups in the CWP it  says Connection_Failed..


Could someone tell me what it is that Im missing...

You need to provide all required details for remote backup did you?

Yes I provided all of the info.
Temp Folder:
Server IP:
Username:
SSH-Port:
Access-Key:

(green Light) Checking if config file exists /usr/local/cwp/.conf/remote_backup.conf.
(green Light)Checking if key file exists /root/.ssh/backup/id_rsa.pub
(green Light)Checking if backup folder /backup exists and creating it if not exists.
(Red Light)Checking if remote connection is tested and activated.

But If I open up putty and run the comman
ssh -i /root/.ssh/backup/id_rsa USERNAME@XXX.XX.XXX.XXX -pXX

I can connect to the Remote server

did you mean that remote backup is working but backup through ssh is not working ?

SSH is working remote is not...
