I don't know if it has been requested, but at this stage of the game, I think it would be quite important to be able to backup and restore a good portion of the server. My thought is the following should be able to be exported and then imported in the case where a server "restore" is necessary:
Users Library Server configuration Watched status/Playstates (you knew it was coming) Installed plugins with configuration for each
I would think those would be the most basic and necessary areas that would be the most difficult to get back in the case of disaster. Metadata and images would be nice, but can be re-scraped.
I just know that at some point, my server will need to be replaced and while I do keep a full backup of all necessary MB3 directories, an integrated recovery solution would probably be much easier for the majority of users.
I know of the backup and restore post here, but I just think it's time for an integrated solution - or even a plugin. I run a daily Windows Server backup job on mine and am confident in restoring it, but I've been in IT for 20 years. General Joe isn't doing that.
