RN102 to Raspberry Pi Rsync over SSH within LAN
Computers - Home - Same LAN RN102 - 2 x 4TB HDD Flexraid OS 6.4.2 Raspberry Pi running latest Raspian - No additional storage Offsite Server - WAN Debian 8.4 based atom server running 24/7 1 x 1TB Office - WAN / VPN possible RN104 - 4 x 1TB HDD Flexraid OS 6.4.2 Flow of data - Offsite Server -> RN102, RN104 (In test scenario) Raspberry Pi -> RN102 (both within the same LAN) Reasoning- I want to incrementally update the home and backup versions from the offsite web hosting, which brings media files down to the RN102 and RN104 in turn, intially I thought the quickest way to create a one way backup would be bittorrent sync. However, files on the web host are constantly deleted which is deleting the data in the backups as well. There are a variety of media files which I would rather backup into the same folder, as in I don't want indiviually dated folders. Rsync seems to fit the bill for this one way sync that simply adds new media and makes no change to the backup folders. If there are any other suggestions on better ways I am game for them. I have been trying for the last week or so to sort out a one way incremental sync between an offsite server running debian and the RN102 / RN104. I thought the easiest way to get a test setup would be to chuck raspian (lightweight Debian) on to the raspberry pi and get a feel for the speeds etc internally, speed is a key requirement and reason for changing to considering rsync. I have not been able to get the setup working at all always getting the 'unable to connect to host' error. I have followed this guide - http://kb.netgear.com/app/answers/detail/a_id/29929/~/readynas-os-6%3A-setting-up-a-backup-job-with-rsync-over-ssh I am really not sure what I am doing wrong, SSH and rsync is enabled on both the RN102 and the Raspberry Pi, I have added the SSH keys to the known_hosts on both units and I am able to SSH to both units from their respective consoles. I am unclear why there would be no route to host as I am able to connect between both, any guidance would be most appreciated.
