There seems to be some confusion with the terminologies being used today around data protection. I hear many people talk about Data Protection Management (“DPM”), backup reporting, disaster recovery when trying to differentiate their offering, which tends to create some confusion when trying to understand the value that each vendor brings and the problem he solves.
Here is OUR short definition of the Data Protection segments:
- Backup – taking a “point-in-time” copy of the data/application. Approaches include backup-to-ALL as well as online snapshots of the data (such as BCV or Clone in the EMC world). Verification tools in this space helps you ensure your backup is complete and optimize the backup process.
- High Availability – increasing business service availability – technologies include virtualization, clusters, raids, load balancing (to some degree) and other hardware tweaks. Verification tools are your typical system management technologies that helps gauge the overall health of your system.
- Disaster Recovery – resume business operation from a remote data center – approach is based on either a shared facility or maintaining a dedicated “mirrored” facility. Technologies include tape-based recovery (ship your tapes to the remote site) and online replication (storage/database/server based) which is based on copying all data to the mirrored site, so you can resume your business service from that site without interruptions.
I would love to hear your opinions and your definition of DPM.
