If you are in read-only mode and you try to upload a backup via gui, the site go ahead and seems to upload the backup even if this is not true.
When you are in read-only mode there should be an alert telling you that you can not load the backup before you disable that mode.
Hmm shouldn’t uploading a backup be OK in read only mode? I am not sure, @zogstrip?
I just tested and uploading a backup while in read-only mode works as expected.
@dax do you have a repro?
Did the backup show up? I was able to upload and get the “uploaded successfully” message, but the backup never appeared in the list.
They take a little while to appear since there is a background task that needs to run in sidekiq to merge the uploaded chunks. Waiting one minute is often enough.
PRO TIP: clicking Logs and then Backups will force a refresh of the backups list.
Closing this but clearly the UI message presented should warn about the refresh @zogstrip that’s the real “bug” here.. and should be fixed.
I’ve added some code to push the new list of backups once the file is merged so it automagically updates
