Summary of "Commvault DR Backup Explained"
Video Summary: Commvault DR Backup Explained
The video titled "Commvault DR Backup Explained" provides a comprehensive overview of the disaster recovery (DR) backup process within the Commvault environment. The key points discussed include:
-
Concept of Commvault DR Backup
The video explains the critical role of the Commvault console (ComServe) and its SQL database, which stores all metadata related to backup operations. In case of a failure (e.g., ransomware attack), the SQL database must be backed up regularly to facilitate recovery.
-
DR Backup Process
The DR backup runs daily at 10 a.m. by default, backing up the SQL database necessary for restoring the ComServe. The backup process involves two phases:
- Export Phase (0-50%): The SQL database backup is staged in a temporary folder within the installation directory.
- Backup Phase (50-100%): The staged backup is then written to a configured library (disk, tape, or cloud).
-
storage policy
A storage policy named "Commvault DR" is automatically created to manage where the DR backups are stored. The first configured library is used by default for storing the backups.
-
Retention Settings
The DR backup retains the latest five copies in the export phase and maintains a retention of 15 days for backups in the library, with extended retention options for weekly and monthly backups.
-
Optional Copies
Users can create additional copies of the DR backup in the Commvault cloud or any configured cloud library, allowing for increased data safety.
-
Manual DR Backup
The video explains how to manually initiate a DR backup and select optional databases and client logs to include in the backup.
-
Challenges
A challenge highlighted is that DR backups stored in libraries are in chunk format, making them unreadable without the ComServe. The video mentions a future discussion on using the Media Explorer tool to extract data from these libraries without the ComServe.
-
Scheduling
Users can modify the scheduling of DR backups to run more frequently than the default setting.
The main speaker in the video provides a detailed guide on the DR backup process, emphasizing the importance of backing up the SQL database regularly and ensuring sufficient storage space is available for staging backups. The next video is promised to cover how to restore the ComServe using the DR backups.
