Wgat is Specific retention?

Specific retention refers to the amount of water that is retained in the soil at a specific tension or pressure. It is a measure of the soil's ability to hold onto water against the force of gravity. Specific retention is important for understanding how water moves through the soil and how much water is available for plant uptake.

Specific retention is a feature in Google Cloud Storage that allows you to define custom retention policies for individual objects. This allows you to protect specific objects from deletion for a specified period of time.

Specific retention overrides the default retention policy set for the bucket. You can define a specific retention policy for an object when you upload it or at any time afterwards.

To define a specific retention policy for an object, you must include a retentionPeriod header in the object's metadata. The retentionPeriod header specifies the number of seconds that the object will be retained.

Once a specific retention policy is set for an object, it cannot be deleted until the retention period has expired. You can view the retention period for an object in the object's metadata.

Specific retention is useful for protecting sensitive or important data from accidental deletion. For example, you might use specific retention to protect financial records, customer data, or medical records.

Specific retention is available for all Google Cloud Storage buckets. However, it is not supported for objects that are stored in coldline or archive storage classes.
