Hierarchal snapshot retention storage

An apparatus, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the apparatus to:
• store, to a storage environment, a first set of first-level incremental snapshots of a target computing object in accordance with a first snapshot frequency, wherein one first-level incremental snapshot in the first set of first-level incremental snapshots comprises differential data relative to a base snapshot of the target computing object, and wherein each other first-level incremental snapshot in the first set of first-level incremental snapshots comprises differential data relative to a respective previous first-level incremental snapshot in the first set of first-level incremental snapshots;
• store, to the storage environment, a first second-level incremental snapshot of the target computing object in accordance with a second snapshot frequency, wherein the second snapshot frequency is lower than the first snapshot frequency, and wherein the first second-level incremental snapshot comprises differential data relative to the base snapshot;
• and
• store, to the storage environment, a second set of first-level incremental snapshots of the target computing object in accordance with the first snapshot frequency, wherein one first-level incremental snapshot in the second set of first-level incremental snapshots comprises differential data relative to the first second-level incremental snapshot, and wherein each other first-level incremental snapshot in the second set of first-level incremental snapshots comprises differential data relative to a respective previous first-level incremental snapshot in the second set of first-level incremental snapshots.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by one or more processors to:

• store, to a storage environment, a first set of first-level incremental snapshots of a target computing object in accordance with a first snapshot frequency, wherein one first-level incremental snapshot in the first set of first-level incremental snapshots comprises differential data relative to a base snapshot of the target computing object, and wherein each other first-level incremental snapshot in the first set of first-level incremental snapshots comprises differential data relative to a respective previous first-level incremental snapshot in the first set of first-level incremental snapshots;
• store, to the storage environment, a first second-level incremental snapshot of the target computing object in accordance with a second snapshot frequency, wherein the second snapshot frequency is lower than the first snapshot frequency, and wherein the first second-level incremental snapshot comprises differential data relative to the base snapshot;
• and
• store, to the storage environment, a second set of first-level incremental snapshots of the target computing object in accordance with the first snapshot frequency, wherein one first-level incremental snapshot in the second set of first-level incremental snapshots comprises differential data relative to the first second-level incremental snapshot, and wherein each other first-level incremental snapshot in the second set of first-level incremental snapshots comprises differential data relative to a respective previous first-level incremental snapshot in the second set of first-level incremental snapshots.
