Accelerator: full vs. incremental schedules
NetBackup Accelerator supports full and incremental backups.
Note: After an initial full backup, Accelerator backups with a full schedule have about the same effect on I/O and performance as traditional incremental backups. The NetBackup catalog however includes all catalog references that would be made if the backup was a traditional (non-Accelerator) full.
Note:
After upgrade from any of the previous release, If the customer has configured accelerator enabled Hyper-v policy, then optimization will be lost only for first backup.
