Backups for Oracle Cloud

Commvault backs up all of the instances identified on the Content tab for a subclient.

Backups of instances are performed in round-robin sequence.

When an instance is discovered during backup, a client for the instance is created in the CommCell Console if one does not already exist. If an instance with spaces in its name is discovered during backup, the spaces are replaced with underscores ('_') when creating the client name that is displayed in the CommCell Console. The instance name with spaces is still displayed on the Instance Status tab for the backup job, in the backup job summary, and in reports that include the name.

Backup Process

Backups include the following stages:

  1. Take a snapshot of each instance.
  2. Create volumes from the snapshots.
  3. Attach volumes to the VSA proxy.
  4. Back up the volumes.

    Incremental backups use CRC to track incremental changes. Backup data goes through the MediaAgent for the storage policy associated with the backup.

  5. Unmount, detach, and delete the volumes and snapshots that were created for the backup.

Backup Types

You can perform the following types of backups, either immediately or on a schedule.

  • Full backups: Back up the entire instance. This is the most comprehensive backup.
  • Incremental backups: Back up instance data that has changed since the most recent backup.
  • Differential backups: Back up instance data that has changed since the most recent full backup.
  • Synthetic Full backups: Consolidate instance data from the most recent full backup with subsequent incremental and differential backups.
