Managing Cloud Storage

In Chapter 11, you saw how to use lifecycle management policies to automatically change a bucket’s storage class. For example, you could create a policy to change a regional storage class bucket to a nearline bucket after 90 days. There may be times, however, when you would like to manually change a bucket’s storage class. In those cases, you can use the gsutil rewrite command and specify the -s flag. Here’s an example:

gsutil rewrite -s [STORAGE_CLASS] gs://[PATH_TO_OBJECT]

Here, [STORAGE_CLASS] is the new storage class. It can be multi_regional, regional, nearline, or coldline.

gsutil mv gs://[SOURCE_BUCKET_NAME]/[SOURCE_OBJECT_NAME] \  gs://[DESTINATION_BUCKET_NAME]/[DESTINATION_OBJECT_NAME]
