auto delete aws S3 backups

I need to automate deletion of aws S3 backups … evidently if I tag the backup with one of daily, weekly, monthly, yearly then aws will delete based on my desired retention counts per those periods however I see no easy way to determine which of those tags I give to my daily backup process which is

//   Upload backup file

aws s3 cp /tmp/backup_2007020644.20200703.1248_blobs.tar  s3://foo-bar-baz-someaccount-us-east-2/backup_2007020644.20200703.1248_blobs.tar --region  us-east-2 --only-show-errors 

aws s3api put-object-tagging --bucket foo-bar-baz-someaccount-us-east-2  --key backup_2007020644.20200703.1248_blobs.tar --tagging  --region  us-east-2 TagSet=[{Key=backuptype,Value=blobs}]

//   now lets list this s3 bucket

aws s3 ls s3://foo-bar-baz-someaccount-us-east-2 --region  us-east-2 

2020-07-01 22:55:57   31904428 backup_2007010938.20200701.2233_blobs.tar

2020-07-03 15:04:46     895279 backup_2007020644.20200703.1248_mongo.tar

alternatively I can code up my own logic to parse above listing then issue the delete command per backup file after my code keeps track of my retention policy … there must be a better way … any advice ?
