Hi.
Thanks a lot for your help.
One of the problems I have is that no-one here has clarified how
important this data is. I'm working on the assumption that it's
'somewhat important', but not critical data (nothing financial or
transactional).
So I don't need quorum; in fact as it will be a read/w
Snapshots take use a hard link and do not take additional disk space

WRT losing a node, it's not the number of total nodes thats important is the
number of replicas. If you have 3 nodes with RF2 and you lose one of the
replicas
Hi.
Cheers for your reply.
Unfortunately there's too much data for snapshots to be practical. The
data set will be at least 400GB initially, and the offsite node will be
on a 20Mbit leased line.
However I don't need the consistency level to be quorum for read/writes
in the production cluster, s
Be aware that at RF 2 the Quorum is 2, so you cannot afford to lose a replica
when working at Quorum. 3 is really the starting point if you want some
redundancy.
If you want to get your data offsite how about doing snapshots and moving them

Hello.
I'm setting up a cluster that has three nodes in our production rack.
My intention is to have a replication factor of two for this.
For disaster recovery purposes, I need to have another node (or two?)
off-site.
The off-site node is entirely for the purpose of having an offsite
backup of t
