Backup restore problem.

[bbav]

Dear administrator：
I encountered a problem recently, that is, I originally used the centos system. After I migrated to ubuntu, I found that the data could not be recovered, and the previous data could not be found in the WEBUI, and I had backed up the configuration file and seed data, and followed the previous data. Paths migrated.
I've tried a lot but can't get it back into the background, hope for an answer, thanks again.

I tried using the option -Automatically add torrents from:
function, but it will be downloaded from a new one?
