About BLI policy attributes

NetBackup applies policy attribute values when it backs up files.

The following attributes must be set for BLI backup:

Policy Type

Set to Standard.

Perform block level incremental backups

Select to enable BLI backups. If the BLI attribute is not enabled, NetBackup uses the standard method to back up the files in the file list.

Job Priority

Set so that the BLI backup policies run before other policies.

Keyword phrase

Define as the Oracle database instance name ($ORACLE_SID) in each of the policies for the same instance. Multistream backups start when all the policies with a particular keyword phrase complete their respective startup scripts. If you have multiple Oracle database instances (SIDs) use a separate set of policies for each SID. If the SIDs are backed up simultaneously and any share a common file system for data files, use Nodata Storage Checkpoints. Set the METHOD to NODATA_CKPT_HOT.

Note:

Do not change a keyword phrase after it is set in a policy. The keyword phrase is used in naming Storage Checkpoints. Changing the keyword phrase necessitates a full backup even if an incremental backup is requested.

The NetBackup Administrator's Guide, Volume I describes other policy attributes and how to configure them.
