DATA RETENTION IN ZONE STORAGE

Abstract:

Methods and systems for data retention in zone storage are disclosed. A method includes: ingesting, by a computing device, a plurality of data objects into a dispersed storage network (DSN); writing, by the computing device, the plurality of data objects to at least one zone on a storage medium in the DSN; determining, by the computing device, that a compaction threshold corresponding to the at least one zone on the storage medium in the DSN is met; determining, by the computing device, that a retention window corresponding to the at least one zone on the storage medium in the DSN has expired; and in response to determining that the retention window has expired, the computing device compacting the at least one zone on the storage medium in the DSN.
