1. A method comprising:
determining an encryption indicator for a first recovery dataset by determining a difference in an amount or percentage of incompressible data associated with the first recovery dataset compared to an amount or percentage of incompressible data associated with a second recovery dataset that temporally precedes the first recovery dataset, the encryption indicator representative of data within or represented by the first recovery dataset that cannot be compressed more than a threshold amount;
determining that the encryption indicator satisfies an encryption indicator threshold; and
preventing, based on the encryption indicator satisfying the encryption indicator threshold, the second recovery dataset from being deleted until one or more conditions are met;
wherein the second recovery dataset is usable to restore data maintained by a storage system to a second state corresponding to a second point in time that temporally precedes a first point in time corresponding to the first recovery dataset.
