Parallel backup processing in OADP

Resource allocation: Increasing the concurrency settings requires additional CPU and memory for the Velero container. Monitor resource consumption to ensure cluster stability.

Backup scope: Parallel processing provides the most benefit for backups that contain a large number of Kubernetes resources or many smaller volumes. Backups dominated by a few large volumes see less benefit because most time is spent waiting for asynchronous data movement to complete.

Namespace partitioning: To keep data integrity, OADP uses namespace-level isolation when processing parallel backups. Two backups cannot run simultaneously if they share any included namespaces.
