NAS to NAS backup (Drobo specific hopefully)  


For years I've been backing up my newer Drobo to my older Drobo using Chronosync on a Mac mini. It works, but it's fragile as all get out. The Mac mini is on WiFi (unavoidable) so it decides to change networks from time to time, there are s/w updates that disengage the Mac mini, Chronosync gets its panties in a bunch about some file, the Drobos dismount in spite of the AppleScript i have running to mount them.
I'm looking for a solution to back up one Drobo to another directly. They're both hard-wired to the same router and sitting smack dab next to each other, so it seems foolish to go over WiFi to a distant room and back and have this Mac in the middle.
I tried Resilio Sync, but it uses SMB and that gets borked up if you also use SMB to access the Drobos. The (good) folks at Resilio told me the only good way to use it would be to have an intermediary device like a Mac (so I'd be back where I started.).
I was looking at OwnCloud and that might be an option but I haven't cracked the (very complex) code on how to set it up. It says I have zero space on all of my shares.
Any ideas?

Good question (and good cause to create a NAS-specific Q&A forum here... I moved your post, @podfeet!).

Is there no longer a 'copy' app on either of your Drobos? Speaking of, which model Drobos do you have? I just found it on my Drobo 5N in the Drobo Apps > Other Applications section. I think it's exactly what you want (but I could be wrong!).

Alternatively you could go in and use 'rsync' from an SSH session, but obviously a little smoother/easier to do it in the GUI/app.


w00t - glad you created a NAS section @davehamilton.  Seemed like there should be one.

I've got a 5N and a 5N2, with my desire to back the 5N2 up to the 5N. I don't see Copy on either one of them in the new firmware. It's highly improved lately, btw.  Pretty icons and better sorting.  


Ok, I must have installed copy on my Drobo from a 3rd-party source. I've checked both DroboPorts and DroboWorks and... nada. Interestingly, if I search for 'copy Droboapps' I find a link to but... it doesn't go where one would expect. Maybe this has been deprecated.


And sadly that's a common occurrence on Drobo's website. There are lots of dead links.  Their support pages where they store their manuals has been down for at least the last 5 days (that's when I notified them and they said they'd "get right on it.")
