Subject Re: Aamzon EC2 & Cassandra to ebs or not..
Date Wed, 09 Mar 2011 16:39:31 GMT
I thought nodetool snapshot writes the snapshot locally, requiring 2x of
expensive storage allocation 24x7 (vs. cheap storage allocation of a ebs
snapshot).  By that I mean EBS allocation is GB allocated per month costs at
one rate, and EBS snapshots are delta compressed copies to S3.

Can you point the snapshot to an external filesystem?
