-w|-verify

This BRRESTORE command option verifies a backup of database files (BRBACKUP) or offline redo log files (BRARCHIVE).

            -w|-verify [use_dbv|only_conf|use_rmv]

Default value: no verification

Possible values:

no value set: only the readability of the backup files on the backup volume is checked, files are not stored on disk
use_dbv: restores files to compress_dir, verifies them with DBVERIFY and then deletes them

Without use_dbv, files are read from backup media but not stored on disk. In either case, a normal restore is not performed.
only_conf: BRBACKUP calls the external backup utility only to confirm that the backup is known, not to verify the data.
use_rmv: restores and then verifies the successfully backed-up files using RMAN

Example

This is an example of how to restore the last backup, followed by a check of the Oracle block structure using DBVERIFY:

brrestore -b last -w use_dbv

This is an example of how to restore the archived offline redo log files nos. 112- 250 and check them for readability:

brrestore -a 112-250 -w
