Abstract
In one example, a method for managing backed up data includes marking a current backup version to indicate that the current backup version has no expiration time, and then determining a currency span for a backup version that immediately precedes the current backup version. Next, one or more curtains crossed by the currency span are identified, each curtain being associated with a respective expiration rule. The expiration rules are then applied to the immediately preceding backup version, and an expiration time assigned to the immediately preceding backup version based on application of the expiration rules.
