Effect of storage class behavior on Accelerator
The following are the affects of the 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 situation happens due to the storage class behavior where the
INODEandCTIMEof the files are changed irrespective of the data or if the metadata of the file is changed.It's a result, due to internal implementation of the storage classes.
