Using cbrestore on multiple nodes

Hi There,
So we have 4 buckets in 4 nodes, configured with 3 replicas.
I just want to check that my understanding of the restore process is correct.
Assuming All nodes go down ( e.g. due to a power failure ), I have setup a new couchbase server with an identical bucket scheme and I need to restore my data. Will running cbrestore on each bucket of any 1 node suffice in order to restore all / the vast majority of data into a new node, or do I have to run cbrestore against every bucket of every node to ensure / virtually guarantee a full restore?
Thanks in advance
Dylan
