I Have a Duo, NV+, & NVX and now it's time for an upgrade. I'm looking at a 516. Will I be able to backup snapshots on the 516 to the older NVs? Rsync is my preferred method and it would be going over a WAN connection after an initial backup.
A snapshot is the NAS frozen at a point in time. Backing up the live data you may get an inconsistent backup.
If an OS6 backup job doesn't create a snapshot before beginning, it should do that automatically (or at least have an option to do so). No need to make getting a consistent backup difficult with btrfs.

Snapshots for the Documents share on the data volume would be stored in: /data/Documents/.snapshots/
You can figure out what path you would like to backup.
Well, not really. They are actually in /data/._share/Documents/.snapshots
In there you will find a list of folders, looking something like "c_1405396809", with different numeric strings. Backing one up automatically (for instance the most recent) would take some effort, and it cannot be done from the web UI. What one might do from the UI is manually clone a particular snapshot, which then could be backed up more easily.
BTW, ryanp, I was not trying to be difficult. Understanding your purpose often helps when answering a question.
On my RN102 I have an "Archive" share with about 500 GB of data. Weekly snapshots are enabled, and at the moment there are about 30 of them for that share. Yes, I could back them up, but it would take 15 TB of space on my older NAS to do so. And that is just one share- and not the largest.
So it is possible but usually not practical. If you search the forums here, you will find a lot of posts from people who are wanting to know how to exclude snapshots from their backup jobs. There is a reason for that.
