NAS to NAS remote cloning frustrations
Maybe its just me, and maybe I dont understand enough about backups (full / incremental / differential etc), but I am really struggling to find a simple solution for a simple problem. Problem: I...
Another option is to use the amazon cloud sync app, though you'd need to pay Amazon for the hosting.
rsync is one-way, it doesn't do two-way sync. Neither does replicate (or any of the built-in backup jobs in the NAS). Backup isn't the same as sync, and you are looking for sync.
There is a guide for rsync here: http://kb.netgear.com/app/answers/detail/a_id/29929/~/readynas-os-6%3A-setting-up-a-backup-job-with-rsync-over-ssh?cid=wmt_netgear_organic
It is missing the port forwarding information (you need to forward port 22 on the system that is responding to the backup job). Also, you'll want ddns configured on that router, so you can reach the far-end system with a URL instead of the public IP address.
Thanks Stephen - good clarity over sync vs backup - and yes I have been mixing the two.
Will do some more research into "NAS sync over internet" then but presume the sync options from this post are:
1) OwnCloud
2) Amazon Cloud
3) BitTorrent Sync
Any preference?

My main method for remote access is openVPN, and I'm not attempting to sync my NAS to other NAS over the internet (though I do have backup NAS on my home network).
I use BT sync some (the selective sync is one way to get NAS files onto my mobile devices). Since I'm still just playing with it, I've chosen to run it on a PC though (the NAS is mapped to a PC drive letter). The appeal for me is that it works in the background. The ability to use QR codes to add folders to mobile devices is also pretty convenient. So my use is quite different from what you want to do. It seems to work ok, though I have seen folders I've deleted on one device re-appear later.
I haven't tried the other two. The files in the Amazon Cloud aren't encrypted (though the connection to the cloud is). If the data is sensitive, that might be a concern. And of course it won't be free. The advantage is that the data is accessible via the cloud no matter where you are - even if the NAS are turned off or not accessible for some reason.
Hopefully other users (particularly folks using OwnCloud) will chime in.
The lack of bandwidth at one of the locations is going to be a problem if I try and use one as the master (and access over openVPN or similar) - its rather rural. Although, as I can leave the NAS connected at that location, I am hoping that running all the time means it can sync effectively. And as it takes me 3+ hours to travel between the two, should be enough for any working files to be sync'd.
I am now testing BTSync at one of the locations and will give it a few conflicts to deal with whilst syncing between my NAS and PC and see what it does.
Paid for cloud services is the one thing I am trying to avoid, as I dont trust them - not 'cos the data is sensitive particularly - although as I didn't employ their server admins I do sometimes wonder... its really because I have been using Livedrive for a number of years, and it's only when I come back to files which are years old do I find some of them unavailable!
I doubt all Cloud services are the same, and some take very good care of your data, but as they're all commercial organisations whose strategy / inverstment / service policies aren't in my control, I subscribe to the view that they are all inherantly unreliable.
As you say, would be good to see how OwnCloud matches up against BT Sync if anyone has used both?

The decision might be a moot one anyway as this page:
https://community.netgear.com/t5/Community-Add-ons/ownCloud-8-0-4/m-p/841071#M2394
...suggests that OwnCloud needs an Intel ReadyNAS and my RN104 isn't....
