# Purpose: A script that loops over ARNS for recovery points and deletes them, with retry mechanism.
# This script assumes usage of aws-vault, adjust command accordingly if needed
# Actually generating the file should be done by yourself (https://docs.aws.amazon.com/cli/latest/reference/backup/list-recovery-points-by-backup-vault.html)

# Variables
FILE="file_separated_with_new_lines_containing_recovery_point_arns.txt"
VAULT_NAME="your-vault-name"
REGION="your-region"
PROFILE="your-aws-vault-profile"

# Function to delete a recovery point with retries
delete_with_retries() {
  local arn="$1"
  local max_retries=3
  local retry_count=0
  local delay=2

  echo "Attempting to delete recovery point: $arn"
  until aws-vault exec "$PROFILE" -- aws backup delete-recovery-point \
      --backup-vault-name "$VAULT_NAME" \
      --recovery-point-arn "$arn" \
      --region "$REGION"; do
    retry_count=$((retry_count+1))
    if [ $retry_count -ge $max_retries ]; then
      echo "Error: Failed to delete $arn after $max_retries attempts."
      return 1
    fi
    echo "Retry $retry_count for $arn in $delay seconds..."
    sleep $delay
    delay=$((delay * 2))
  done
  echo "Successfully deleted $arn"
}
