CloudRanger has the ability to import existing backups into a backup policy.
This process is done through tagging. EBS Snapshots, AMIs or Redshift Snapshots can be imported into a Backup Policy. Backups can be imported if they are tagged with a specific tag or they can also be imported if they have no tags.
Reviewed Before Importing Backups
A review of the Backups to be imported to a Backup Policy is then required before they can be officially imported.
When IMPORT is selected these resources are then applied to existing Backup Policy and the retention of these new backups will be handled by that policy.
An easy way for managing tags on existing snapshots is through the AWS Management Console - Tag Editor.
