Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

System (VxFS) available through Veritas Storage Foundation for Oracle. BLI
Backup reduces both the time required to complete a database backup and the
amount of data transferred during backups. It also allows more frequent backups,
resulting in more up-to-date backup images. When restoring from backups, the
restore time is increased only by the extra time needed for NetBackup to apply
the incremental backups after a full restore completes. However, frequent
incremental backups can speed up the database recovery by reducing the number
of redo logs to apply.
BLI Backup is particularly useful in a database environment where a database can
be hundreds of gigabytes or terabytes. Using traditional backup methods for an
offline database backup, any change in the database file—no matter how
small—requires backing up the entire database file. Using BLI Backup, only
modified data blocks need to be backed up.
Note: To allow BLI Backups, the database must be on VxFS file systems using the
Version 4, 5, 6, or 7 layout, and you must have a valid Veritas Storage Foundation
license. Use the command to determine the layout version of your file system.
See the (1M) manual page for more information.
See “Upgrading from earlier VxFS version layouts ” on page 179.
