Backup using rsync – what options are used
Rsync is a robust Linux file copy program with lots of options http://linux.die.net/man/1/rsync is a great discussion of the features and options. . http://serverfault.com/questions...
Sounds like you may be on your way to a solution.
FWIW, I got my ReadyNAS up into operating condition today and have the following to report regarding the rsync command as issued from the GUI
rsync -v -8 --timeout=30 --recursive --links --times --devices --specials --one-file-system --modify-window=1 --owner --group --no-acls --no-perms --exclude CrashPlan --exclude Downloads --exclude Library/logs --exclude Library/Caches --rsh=ssh -o SrticHostKeyChecking=no -PasswordAuthentication=no -p 22 name@host:/SourceShare /data/DestShare
Good luck!
EDITED TO ADD:
I forgot to say that this is Rsync over ssh with the following options
NO - enable compression
NO - remove deleted files on target
I DO have a list of excluded files/folders, but it seems the gui is programmed also to include .snapshots in that exclusion list
Schedule Full backup: "First Time Only"
NO - Remove Contents before
NO - Change ownership

How could I make the snapshots not browseable – the idea is intriguing. I want to explore.

There is a checkbox for each share for "Allow Snapshot Access". All you need to do is make sure it is unchecked.
Though the Windows systems still have some access to the snapshots. If users right-click on a changed file or folder, they will see "restore previous versions", which accesses the snapshots. Some malware might be able to access them also. However, I'd still recommend disallowing snapshot access (assuming of course that you enable snapshots in the first place).

Your cautionary warning about the newness of the BRFS technology to the platform is very useful – it says wait a while.
The OS 6 platforms with BTRFS were introduced about 2 years ago. So its not that new.
Thank you for taking the effort to comment.
My original question was what options the ReadyNAS rsync implementation uses for its copy when activated via the UI.
The other question is if it is possible to change those options somehow without going deep into the system with kernel access.
Any leads on those answers would be appreciated.

I don't recall off hand - perhaps netgear can comment. If you have ssh access, you can see the options if you run top while a backup is in progress. There's a "c" toggle that shows the command line (or not).

You would need ssh access to change them. I've never tried to do that, but I suspect it might be difficult.
An easier path might be to directly create your own back-up cron jobs, and not use frontview backup. You could write the logs to a share, so status could be easily seen. Though you wouldn't get alerts on failure.
Thanks for the reply.
All good information but …
Your suggestions are stretching my technical knowledge and most definitely my available time.
50+ remote sites and no technical personnel means no SSH access will be allowed.
No alerts, not really feasible from a management perspective.
We like supported solutions – money is less an issue than reasonable support for the integrated solutions. Unfortunately, aside from a great NAS product, the current ReadyNAS environment is more like a toolbox – good solutions for some stuff but not integrated and RTG.
I was/am hoping someone will see this post and offer/suggest their solution that is already integrated with the appropriate GUI – similar to what we find in the Windows environment.
HI Bains,
Just to follow up. Are the ReadyNAS units running OS 6?
