The plan associated with Amazon hypervisors and VM groups manages scheduled backups. You can also perform on-demand backups at any time.
You can configure IntelliSnap backups on the VM group. If an instance fails to back up during an IntelliSnap backup of a VM group, the backup job is marked as completed with errors.
Changed Block Tracking (CBT) Based Backups
CBT-based backups enhance the backup performance of AWS volumes. You can use CBT with streaming backups, and with the backup copy operation of IntelliSnap backups. By default, CBT is enabled when you create a new VM group. You can also enable CBT for existing VM groups. For more information about CBT for Amazon, see Changed Block Tracking for Amazon.
