Support and usage of AWS resource tags for Amazon EC2 protection

For backups of Amazon EC2 and related resources, the Commvault software creates intermediate resources, such as snapshots and volumes, to read data from the source volumes. These intermediate resources inherit all the tags that are associated with the source volumes. When you restore Amazon EC2 resources, such as instances and volumes, Commvault restores all tags that are associated with the resources.

Commvault supports the use of AWS tag policies. Tag policies in your environment must not prevent Commvault from adding tags.

Name	CV_CBT_SNAP If CBT is enabled, after every backup operation, the most recent AMI is retained and the CV_CBT_Snap tag is added to the snapshot. 15 days after the CV_CBT_Snap snapshot is created, if no new backups are run on the instance, the snapshot is deleted. To retain CV_CBT_Snap snapshots for longer than 15 days, use the nSnapshotRetentionDays additional setting.	AMIs Snapshots	Backup
