Backup OS 6 snapshots to older ReadyNas?
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.
Thanks in advance.
Thanks in advance.

You can backup shares on the 516 to the older NAS.
More than likely you don't want to back up the 516 snapshots.

Yes, backing up the snapshots is exactly what I want to do.
Maybe someone knows if this would work.

Why?

Each snapshot will consume the full space of the share on older NAS. It will not be stored as a delta.

Bingo! This is why I was asking if I can back up the snapshots.

Re: Backup OS 6 snapshots to older ReadyNas?
A snapshot is the NAS frozen at a point in time. Backing up the live data you may get an inconsistent backup.
It should be possible to backup snapshots.
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.

Re: Backup OS 6 snapshots to older ReadyNas?
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.

Well, not really. They are actually in /data/._share/Documents/.snapshots

You can figure out what path you would like to backup.
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.
