Understanding the features of D-NAS
This table explains the salient features of data protection using D-NAS.
Table:
Feature | Description |
|---|---|
Convenience of backup host pool | Backup host pool is a group of NetBackup backup hosts where the snapshot of the volume is staged for the backup process to read. These hosts can be NetBackup client, media, or primary server. |
Vendor change tracking | Vendor change tracking (VCT) is a mechanism to get the difference in the content of the volume or share between two points-in-time snapshots. It relies on storage array vendor's native technology to identify the difference, that is, add, modify, and delete files between two point-in-time snapshots of the same volume. You must ensure that the storage array you are using, provides such a capability in order to use this feature. VCT is not applicable in the following conditions:
|
Exclude volumes | You can exclude the volumes out of the backup selection list
that you do not want to backup.
For example, |
NetBackup accelerator | NetBackup's robust accelerator feature can be leveraged along with dynamic streaming for optimized and fast backups. |
Checkpoint restart | You can leverage NetBackup's checkpoint restart feature along with dynamic streaming. By taking checkpoints periodically during the backup, NetBackup can retry a failed backup from the beginning of the last checkpoint without restarting the entire job. |
