I just came up with a toolkit written in shell script requested by Sathish Murphy that could help with backing Oracle database to tapes or VTL using NetBackup or CommVault.
The pre-script puts an Oracle DB in backup mode, take snapshot, take DB out of backup mode, creates clones and mount on the backup media server. Once mounted, NetBackup or CommVault can send data to tape or VTL.
The post-script unmount file systems, remove clones, and delete snapshot.
These scripts are for any backup software that has the pre and post script capability and only run on Linux operating system. Make sure to read the README-FIRST before implementing the scripts.
