You can perform backups automatically based on the configuration for a hypervisor or VM group, or manually for a VM group or a specific instance.
The first backup of an instance is always a full backup. By default, all subsequent backups are incremental, capturing any changes to instance data since the last backup.
You can recover instance data, even when the most recent backup was incremental.
Oracle Cloud Infrastructure incremental backups utilize Cyclic Redundancy Check (CRC) validation in order to determine which blocks have changed since the last backup. Due to this validation process, incremental backups may take as long to run as full backups.
