The plan associated with Amazon EC2 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 have better performance for Amazon EC2 instances. 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 enable CBT for existing VM groups.
For more information about CBT for Amazon, see Changed Block Tracking for AWS.
Job Statuses for Backup Copy Operations
For Feature Release 19 and more recent feature releases, when an IntelliSnap backup includes multiple VMs, if a backup copy job for a specific VM cannot be completed, the backup copy job goes to pending and then retries the backup copy operation, up to the maximum number of job attempts that is configured for the Job Manager. (By default, the number of job attempts is 10.)
Any backup copy jobs that do not complete successfully after the maximum number of attempts are marked as Completed with Errors. If backup copy jobs for any VMs do not complete successfully after the maximum number of attempts, the associated IntelliSnap backup job is marked as Completed with Errors.
For service packs prior to Feature Release 19, if a backup copy operation was successful for any VM in an IntelliSnap backup job, the IntelliSnap backup job was marked as Completed with Errors if backup copy operations were unsuccessful for other VMs that were part of the IntelliSnap backup job, and any unsuccessful backup copy operations for the remaining VMs were not retried.
