IMHO this is a bad idea.
* You secondary DC will have no redundancy, when you restart it you will be
relying on HH and nodetool repair.
* If your secondary DC machine fails so does the singe copy of your backup.
* There will be additional management overhead for managing an unbalanced DC.

Hi Aaron,
Thank you for your answer!
My idea was to do the snapshots in the backup DC only. That way the backup
procedure will not affect the live DC. However I'm afraid that a
point-in-time recovery via the snapshots in the second DC (first restore
backup on backup DC and then repair live DC) wi

Hi Aaron,
We have many deployments, but typically:
- Live cluster of six nodes, replication factor = 3.
- A node processes more reads than writes (approximately 100 get_slices
per/second, narrow rows).
- Data per node is about 50 to 100 GBytes.
- We should recover within 4 hours.
The idea is to
You can consider using a WAN optimization appliance such as a Riverbed
Steelhead to significantly speed up your transfers, though that will cost. It
is a common approach to speed up inter-datacenter transfers. Steelheads for the
AWS EC2 cloud are also available.

Honestly, at this point I don't think anyone can provide you any good
feedback based on facts because
Thank you. I have a high bandwidth connection. But that also means that
regular repairs on the backup data-center will take a long time.

Hello,
If the live data centre disappears restoring the data from the backup is
going to take ages especially if the data is going from one data centre to
another, unless you have a high bandwidth connection between data centres
or you have a small amount of data.
