About policy attributes
With a few exceptions, NetBackup manages the policy attributes set for a database backup like a file system backup. Other policy attributes vary according to your specific backup strategy and system configuration.
For more information on policy attributes, see the NetBackup Administrator's Guide, Volume I.
Table: Policy attribute for NetBackup for Exchange policies
Attribute | Description |
|---|---|
| Determines the types of clients that can be backed up with the policy. For Exchange databases, select the policy type MS-Exchange-Server. |
Note that in a Database Availability Group (DAG) environment where the Exchange server is a both a client and a media server, policy storage is treated differently. If you want to back up to the local Exchange client that is also a media server, specify a storage unit group. NetBackup automatically selects the local storage unit from the storage unit group during the backup processing. If you specify a single storage unit, all backups use this storage unit. | |
| Specifies that NetBackup can divide automatic backups for each client into multiple jobs. Each job backs up only a part of the list of backup selections. The jobs are in separate data streams and can occur concurrently. The number of available storage units, multiplex settings, and the maximum jobs parameters determine the total number of streams and how many can run concurrently. Not all directives in the backup selections list allow for multiple database streams. You can create multiple data streams at the database level. |
Allows restores of individual items using Granular Recovery Technology (GRT). Users can only restore individual items from a full backup. (You can perform incremental backups using GRT, but the backup does not save granular information and you cannot restore individual items from an incremental backup.) You can restore individual items only if the backup image resides on a disk storage unit. If you want to retain a granular backup on tape, you must duplicate the image. If you want to restore from a granular backup that was duplicated to tape and the disk image expired, you must duplicate it back to a disk storage unit. If you expire all the copies of the backup image and then import the data files back into the catalog, the mailbox lists are not re-created and you can no longer use that image for granular restore. Exchange GRT-enabled backups do not support encryption or compression. | |
| A textual description of a backup. Useful for browsing backups and restores. |

For Exchange backups, you must enable the option for all backup policies. For VMware backups, this option is enabled automatically. See About configuring a VMware backup that protects Exchange Server. See Configuring VMware application backups that use Replication Director. |
Microsoft Exchange Attributes | Indicates what database backup source you want to use for a DAG. You can also indicate a preferred server list. See Backup source for a Database Availability (DAG) backup . See Configuring a preferred server list for a Database Availability Group (DAG). |
