Re: Backup
Geez, I love how these 'experts' who don't work with data at scale talk about taking snapshots and backups.
News flash... Hadoop has been around for 10 years now. You don't take backups of hadoop clusters. you take snapshots and xfer the data to another cluster. The cluster's resiliency and backup to another cluster is it. What, you're going to back up to tape? Really? As someone with half a shred of thought points that its not the incremental backup that takes time.. but the restoring of the data.
