Abstract
Techniques for managing snapshots of a storage object in a data storage system based on the data churn delta between the latest snapshot and the current data of the storage object. The techniques include, having specified minimum and maximum data loss tolerances for a parent object, creating successive snapshots of the parent object, each snapshot being created at a scheduled time interval or a time when the minimum data loss tolerance has been reached/exceeded. The techniques include obtaining the total data churn between the latest snapshot and the parent data, and determining whether the total data churn has reached or exceeded the maximum data loss tolerance. The techniques include, having determined that the total data churn has reached or exceeded the maximum data loss tolerance, retaining only those snapshots that have not exceeded the maximum data loss tolerance, and discarding all snapshots that have exceeded the maximum data loss tolerance.
