I noticed changes in the design docs, so I am creating this ticket and adding sub-tasks to ensure we have covered these changes in the documentation:

CSI snapshots copied to the protected namespace and copied off cluster using kopia

• Components: CSI, Kopia
  • CRD’s: DU, DD, 
  • DataUpload, DataDownload

• • Configuration: NodeAgent configured
  • Eliminates complex configuration

• • Execution: backup option
  • Pods: Part of Velero
  • Data Transfer: Kopia

• VolumeMode Block Support
  • OpenShift Virtualization defaults to block mode volumes. These block mode volumes can now be supported by OADP.  Performance enhancements and improvements will be considered in future releases.  Consider this basic support.
  • Requires a privileged node-agent

• Performance
  • OADP-1.2.x allows a user to configure maxConcurrentBackupVolumes and maxConcurrentRestoreVolumes. The DataMover feature in OADP-1.3.x allows one volume to be copied off the cluster per worker node.   Future releases of OADP-1.3.x will allow a user to configure more than one volume per worker node.
  • CPU and Memory Notes:
  • DataMover with kopia can be very performant but CPU and memory intensive.  When the appropriate resources are provided data movement can be more than twice as fast as OADP-1.2.  Performance testing is on-going.
