Abstract
A database may store a plurality of database revisions corresponding to a time period, including a current version and one or more backup versions of a data object. After a threshold time has passed, the database may identify a plurality of time intervals within the time period and identify, for each of the plurality of time intervals, at most one database revision corresponding to the time interval. The database may delete, for each of the plurality of time intervals, all of the database revisions except for the identified at most one database revision. The database may periodically repeat this process to reduce the granularity of backup data over time.
