Subject Snapshotting to a different volume?
Date Thu, 19 May 2011 00:37:55 GMT
As of 0.8.0, is it possible to take a Cassandra snapshot to a different
volume (like a EBS volume dedicated for backups)?

About a year ago, Jonathan Ellis said that this won't be implemented b/c
snapshots are basically hard links:

But I don't fully understand that. If a snapshot is just a hardlink, won't
the snapshot also change as new data is written to the SSTables?
