Immutable storage of snapshot data in a public cloud environment

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:
• perform, at a first time, a first scan job to determine whether to extend respective immutability periods for snapshot data entities within a set of snapshot data entities, wherein, for a snapshot data entity of the set of snapshot data entities, a respective retention period for the snapshot data entity comprises a duration of time until the snapshot data entity is eligible for deletion and a respective immutability period for the snapshot data entity comprises a duration of time during which the snapshot data entity is immutable;
• extend, based at least in part on the first scan job, the respective immutability period for a first snapshot data entity within the set of snapshot data entities based at least in part on the respective retention period for the first snapshot data entity being greater than or equal to a threshold duration;
• perform a second scan job at a second time after the first time;
• and
• maintain, based at least in part on the second scan job, the respective immutability period for the first snapshot data entity based at least in part on the respective retention period for the first snapshot data entity being less than the threshold duration.

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

• perform, at a first time, a first scan job to determine whether to extend respective immutability periods for snapshot data entities within a set of snapshot data entities, wherein, for a snapshot data entity of the set of snapshot data entities, a respective retention period for the snapshot data entity comprises a duration of time until the snapshot data entity is eligible for deletion and a respective immutability period for the snapshot data entity comprises a duration of time during which the snapshot data entity is immutable;
• extend, based at least in part on the first scan job, the respective immutability period for a first snapshot data entity within the set of snapshot data entities based at least in part on the respective retention period for the first snapshot data entity being greater than or equal to a threshold duration;
• perform a second scan job at a second time after the first time;
• and
• maintain, based at least in part on the second scan job, the respective immutability period for the first snapshot data entity based at least in part on the respective retention period for the first snapshot data entity being less than the threshold duration.
