High water mark storage unit setting
The storage unit setting applies to storage units and to disk pools.
Note:
High water mark does not apply to cloud storage disk pools. This value is derived from the storage capacity, which cannot be fetched from the cloud provider.
The setting (default 98%) is a threshold that triggers the following actions:
When an individual disk volume of the underlying storage reaches the , NetBackup considers the volume full. NetBackup chooses a different volume in the underlying storage to write backup images to.
When all volumes in the underlying storage reach the , the storage is considered full. NetBackup fails any backup jobs that are assigned to a storage unit in which the underlying storage is full. NetBackup also does not assign new jobs to a storage unit in which the underlying storage is full.
NetBackup begins image cleanup when a volume reaches the ; image cleanup expires the images that are no longer valid. NetBackup again assigns jobs to the storage unit when image cleanup reduces any disk volume's capacity to less than the .
If the storage unit is in a capacity-managed storage lifecycle policy, other factors affect image cleanup.
