About script-based Block-Level Incremental (BLI) Backups without RMAN
NetBackup for Oracle with Snapshot Client extends the capabilities of NetBackup to back up only changed data blocks of Oracle database files. NetBackup recommends using RMAN-based BLI backups, which allows tight integration with Oracle administration.
If you choose to use script-based BLI backups without RMAN, you can configure NetBackup for BLI support. A BLI backup backs up only the changed data blocks of Oracle database files. NetBackup for Oracle script-based BLI performs backups using the Storage Checkpoint facility in the Veritas File System (VxFS) available through the Veritas Storage Foundation for Oracle.
