Subject Snapshots V. SSTables2Json
Date Wed, 21 Sep 2011 14:17:33 GMT
When planning a DR strategy, which option is going to, most consistently,
take the least amount of disk space, be fastest to recover from, least
complicated recovery, ect?

I've read through the Operations documents and my take is this so far.  If I
have specific column families I want to snapshot across the cluster, then
sstables2json would make the most sense.  However, if I want to back  up an
individual node(s), so that I can better and more quickly recover from a
node failure then snapshots would make more sense?

Regularly backing up the data on a large cluster with a high replication
factor is redundant, but in a situation where you have an RF <= 2, and are
located in a single rack / datacenter, then it might make sense to implement
something like this to backup and store data offsite, and I'm trying to
figure out  what a good, viable, and storage efficient plan would look like.
