Extracting Backup Metadata from OCI Object Storage

Use this procedure to extract the backup metadata from OCI Object Storage and store the information in an XML file.

If your database backups are stored in OCI Object Storage, then you can use the odbsrmt.py tool to manually extract the backup metadata into an XML file. The odbsrmt.py tool is available in the same directory where you have downloaded the SBT library while installing the backup module.

On the database server, install the Oracle Database Cloud Backup Module for OCI Classic module if you are using the Swift APIs to access Object Storage. If you are using the OCI native APIs, then install the Oracle Database Cloud Backup Module for OCI module.

Run the odbsrmt.py tool on the database server by providing the mandatory parameters and their values.

If you are using the Swift APIs to access an Object Storage bucket, then provide these mandatory parameters and values to generate a backup metadata XML file.


--mode=rman-listfile
--ocitype=classic
--credential=user name for your cloud backup module for OCI Classic account/password
--host=REST endpoint for the OCI Classic account
--container=Name of the storage container that contains the source database backups
--forcename=Specify a name for the metadata XML file
--dir=Directory to store the metadata XML file
--dbid=The DBID of the source database
--prefix=The common prefix used in the backup piece names

If you are using the OCI native APIs to access an Object Storage bucket, then provide these mandatory parameters and values to generate the backup metadata XML file.


--mode=rman-listfile
--ocitype=bmc
--uocid=User OCID for the Oracle Cloud Infrastructure account
--tocid=Tenancy OCID for the Oracle Cloud Infrastructure account
--pubfingerprint=public key used to authenticate OCI API requests
--pvtkeyfile=private key used to authenticate OCI API requests
--host=REST endpoint for the OCI account
--container=Name of the bucket that contains the source database backups
--forcename=Specify a name for the metadata XML file
--dir=Directory to store the metadata XML file
--dbid=The DBID of the source database
--prefix=The common prefix used in the backup piece names

The rman-listfile mode generates the backup metadata in an XML file that can be read by RMAN to perform a DUPLCIATE operation of the source database. You can run the DUPLICATE command along with the BACKUP LOCATION FROM FILE backup_list_file clause to specify the XML file required for duplication. See Backup and Recovery Reference for more information.
The odbsrmt.py tool searches a bucket or container for backup piece names that start with the specified prefix.

This example shows how the odbsrmt.py tool creates a backup metadata file duplicate.xml for a database backup stored in the Object Storage container PRODBACKUPS


$ $ORACLE_HOME/bin/python /home/oracle/OPC/lib/odbsrmt.py 
--mode=rman-listfile
--host= https://myDomain.storage.oraclecloud.com/v1/myService-myDomain/
--ocitype=classic
--credential='myAccount@myCompany.com'/'account-password'
--container=PRODBACKUPS
--forcename=duplicate.xml 
--dir=/home/oracle/OPC 
--dbid=2500571935
--prefix=CloudBkp

odbsrmt.pl: ALL report output will be written to [/home/oracle/OPC/duplicate.xml]

python ./ocilib/odbsrmt.py

This example shows the sample contents of an XML file that contains the backup metadata.
