On Discourse latest beta, docker install, multisite. Trying to restore a backup with original database REDACTED to current database db8015. Uploads end up in default, both on filesystem and in database. This happens both when the restore is triggered from the GUI, and when the restore is done on t…

Just to clarify, repro is: Create a multisite in a docker container Backup one of the multisites In a new docker container restore it Uploads are in the wrong place @kris.kotlarek can you repro this on local and see if you can fix it? I suspect we will be hit by this in future.

Only the destination container needs to be multisite to repro this. Create a forum in a docker container Create a backup In a new multisite docker container restore it Uploads are in the wrong place

Thanks! After giving this some more thought, what does it even mean when db:dump is ran on something which is not the primary database? Shouldn’t it just skip the db:dump command if database is not default?

Fixed was merged, thank you for finding that issue. That dump command was added because there was a problem with multisite migrations. I think that It shouldn’t matter which database we are using to dump structure because all multisites should have same structure.
