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.
For virtual machine restore, note the following about full vs. incremental backups with Accelerator:
For applications (Exchange, SQL, and SharePoint), NetBackup Accelerator supports Granular Recovery Technology (GRT) restores from full backups only.
For any other kind of virtual machine restore, the Accelerator supports full backups and incremental backups.
