I have a 20TB RAID6 volume that is attached via Thunderbolt 2 that I am attempting to backup to the Drobo 810N.
The 810N is attached to the computer via my gigabit office network (it’s a modest traffic network, so speeds are always good), and has a static IP address so I can mount it via afp (afp instead of SMB because I have been led to believe that I need to do that to be able to create a sparsebundle)
When I try and clone the Thunderbolt volume, it chugs away for 2-5 days (expected) before the drobo simply disappears from CCC, and the cloner throws an error - but then the 810N is still mounted and accessible from the Finder.
I have tried doing this both via a simple clone, and also creating a sparsebundle on the Drobo, with the same results.
I did contact CCC support, and they told me that trying to clone such a large volume via the network is highly inefficient. They said that the sheer number of filesystem transactions is choking the process, but maybe it will eventually work.
Can anyone shed more light on what’s happening? Is there a way to maximize the potential for success? I’ve spent quite a bit of $ on the 810 and drives, and it would be a real shame if it’s not a viable solution for backing up my storage.
