How StorageGRID Webscale ILM rules manage objects

The grid administrator creates information lifecycle management (ILM) rules to manage object data ingested into the StorageGRID Webscale system from S3 REST API client applications. These rules are then added to the ILM policy to determine how and where object data is stored over time.

ILM settings determine the following aspects of an object:

Geography
The location of an object’s data within the StorageGRID Webscale system.
Storage grade
The type of storage used to store object data (disk or archival media).
Loss protection
How copies are made: replication, erasure coding, or both.
Retention
The changes over time to how an object’s data is managed, where it is stored, and how it is protected from loss.

ILM rules can filter and select objects. For objects ingested using S3, ILM rules can filter objects based on the following metadata:
