Migrate to Swift primary storage


I would like to migrate my files (about 100GB) from a block storage to an object storage (Openstack Swift)

I’ve seen this tutorial: https://pedal.me.uk/migrating-a-nextcloud-instance-to-amazon-s3/

It shows several steps:

I began to do all this but I noticed the same files are present in ‘home::%’ and ‘local::%’ storages. I’m not sure that’s a good idea to transfer files twice with different names on the container.

Could someone explain the difference between files in ‘home::%’ and ‘local::%’ storages please? And how avoid having dupes?
