Amazon RDS for MySQL states the following:
There is no additional charge for backup storage, up to 100% of your total database storage for a region. (Based upon our experience as database administrators, the vast majority of databases require less raw storage for a backup than for the primary dataset, meaning that most customers will never pay for backup storage.)
As far as I understand from searching the internet, they are taking incremental snapshots of the EBS volume. And retention period that can be selected is between 1 days and 35 days.
Could someone with experience comment on what percentage of storage will be required for a retention period of 35 days please? Is the above statement by Amazon for this maximum period?
