Duplication & Rsync issues...

[wtfR6a]

I want to migrate data from an old FreeNAS system to a new FreeNAS machine. Volume duplication as far as I can see produces only a read only backup of the data which isn't much use in respect to decommissioning the old system.
Rsync has the bug where windows shares copy the directories but not the files within.
Is there a tweak/best-practice/other way to allow me to undertake this migration quickly and safely?

zfs replication is usually the tool people use for this.

Making the replicated dataset(s) writable afterwards should be no problem

Never had to do this myself, though.

Rsync will work; you just have to avoid the problematic command-line options. See these two threads here on the forum:

• "Imparied Rsync permissions support for Windows datasets"
  
• "Easy Rsync task creation?"

Replication doesn't make anything read-only if you use zfs send and receive.

FreeNAS is setting ZFS property readonly=on on datasets at destination side [...] if one uses the GUI to accomplish the replication task.

See for example the bottom of this page.

This feature was introduced in Feb 2016, as far as I remember.

Not if you just use zfs send and receive from the command line.

Thanks guys, some things to look into for sure. I have tried to avoid using the command line not because I'm not comfortable with it but for fear of disrupting some GUI / appliance thing.

My preference was to use rsync as it can send over the SSH session unencrypted/decompressed which maximizes throughput but happy to use ZFS replication if it works too. I'll work through the above links and info, thanks again.
