Is it possible to restore files from a remote Plesk backup (FTP/Cloud storage) without downloading the whole archive?
In Plesk Obsidian, when restoring individual objects (for example, one subscription) from a remote Plesk backup, only a backup of a subscription will be downloaded.
Note: If two or more subscriptions are restored at once, the full archive will be downloaded anyway.
In Plesk Onyx, the whole backup is downloaded from remote storage.
Also, the corresponding feature request with ID PPM-2517 exists and it will address this behavior.
It is going to be implemented in future Plesk releases.
