+      Removes locally cached copies of media attachments from other servers.
+
+      The --days option specifies how old media attachments have to be before
+      they are removed. It defaults to 7 days.
+
+      With the --background option, instead of deleting the files sequentially,
+      they will be queued into Sidekiq and the command will exit as soon as
+      possible. In Sidekiq they will be processed with higher concurrency, but
+      it may impact other operations of the Mastodon server, and it may overload
+      the underlying file storage.
