Impact of storage class behavior on accelerator

Following are the impacts of storage class behavior on accelerator:

  • For Kubernetes accelerator enabled backups, NetBackup shows optimization based on the amount of data changed.

    However, the duration to complete a subsequent accelerator job can be similar to complete a full backup job.

  • This happens due to the storage class behavior where INODE and CTIME of the files gets changed irrespective of the data or metadata of the file is changed.

  • It's a result, due to internal implementation of the storage classes. For more details, refer to the Red Hat Knowledgebase articles on the customer portal site: https://access.redhat.com/solutions/7036388
