Subject RE: Backup Cassandra to
Date Thu, 12 Jun 2014 13:11:24 GMT
So you have to install a backup client on each Cassandra node. If the 
NetBackup client behaves like EMC Networker, beware the resources 
utilization (data deduplication, compression). You could have to boost 
CPUs and RAM (+2GB) of each nodes.

Try with one node: make a snapshot with nodetool and configure NetBackup 
so the backup client sends data to your tape library or virtual tape 
library. And of course, try to restore ;-)
The tricky part is not Cassandra itself, it's to follow NetBackup (or 
whatever) best practices.
