==== {api-description-title}
|
|
|
|
Over time, snapshot repositories can accumulate stale data that is no longer
|
|
referenced by existing snapshots.
|
|
|
|
While this unreferenced data does not negatively impact the performance or
|
|
safety of a snapshot repository, it can lead to more storage use than necessary.
|
|
|
|
You can use the clean up snapshot repository API to detect and delete this
|
|
unreferenced data.
|
|
|
|
[TIP]
|
|
====
|
|
Most cleanup operations performed by this API are performed automatically when
|
|
a snapshot is deleted from a repository.
|
|
|
|
If you regularly delete snapshots, calling this API may only reduce your storage
|
|
slightly or not at all.
