New features for BRBACKUP, BRARCHIVE and
1. Consistent online backup: The
online redo log files generated during the online backup
(backup_type = online_cons) are also saved by BRBACKUP. This
ensures that the backup contains logically consistent data.
2. Structure retaining database copy:
Using BRBACKUP (backup_type = disk_copy) you can make a copy of the
database in which the directory structure is adopted exactly.
3. Backing up data tablespaces: When
backing up (backup_mode = all_data) or reloading using BRRESTORE
you can reduce the volume of data by excluding the pure index
4. Two-phase backup with BRBACKUP and
BRARCHIVE: The first phase makes a backup to disk and the second
phase makes a backup of the disk backup to tape. The advantages of
this are the short backup time, usage of BRBACKUP and BRARCHIVE
volume management and new options when restoring the
5. BRBACKUP and BRARCHIVE backups in
one run: BRBACKUP backups of the database files and BRARCHIVE
backups of the offline redo log files can be performed in one run.
This enables you to make more effective use of tape capacity and
eases unattended backups. The whole backup can be made under the
control of BRBACKUP(brbackup -a) or BRARCHIVE(brarchive -b).
6. Verification of backups with
DB_VERIFY: You can apply the ORACLE DB_VERIFY check on the ORACLE
internal block structure to reloaded BRBACKUP backups, or apply it
online to database files.
7. Independent verification of
backups: BBRESTORE -verify allows you to make the verification at a
point in time independent of the backup.
8. Completion of BRBACKUP and
BRRESTORE runs: BRBACKUP -fillup allows you to complete terminated
backups or check the completeness of partial backups. You can also
complete terminated reloads using BRRESTORE -fillup.
9. Backups with jukeboxes and
autoloader: In this type of backup the (backup_type =
tape_box|pipe_box) backup devices select and mount the tapes in an
arbitrary sequence. The programs, shell scripts or batch files for
mounting or demounting the tapes are created by the user and
defined in the profile paramater mount_cmd or dismount_cmd.
10. Split mirror disks backup: By
backing up the mirror disks to a secondary host (online or offline)
you can minimize downtime when making an offline backup.
11. Reloading individual files from
backed up directories.
