A changed password or host name could only be handled by adding a new location, which starts an empty repository and, with a retention lock at the provider, keeps the old one billed. Edit now changes a location in place (web interface and occ backup:target:edit). The settings are only saved when they lead to the same repository; a failed connection and a missing repository give separate errors, and the folder is not created while checking. Stored passwords are never sent to the browser: an empty password field keeps the stored value.
