Lifecycle Management Overview
Lifecycle management applies to the following scenarios:
You can define lifecycle rules for identifying objects and manage lifecycles of the objects based on the rules. After unnecessary files are deleted, less OBS storage space is required, saving your costs.
Objects that are no longer frequently accessed are transitioned to Warm or Cold, further saving your costs. In short, transition basically means that the object storage class is altered without copying the object. You can also manually change the storage class of an object on the object page.
