Restoring backup data does not work.

[nobbywfc]

I have been using Version: v0.23.1 since a month or so by deploying it as container.
OS is ubuntu Jammy. Web server is Nginx.

During SSL installation for this container app, the setting procedure was helped with Gmini, I have changed default nginx conf file and that installation was successful.
But my data has been lost. Data restoring from volume was not successful nor data restoring from manually backed-up file.

What I had done for retoring from manually backe-up file is as follows

docker stop memos
docker rm memos

ls -lt ~/.memos

:~/.memos$ ls -lt
total 15824

cp ~/.memos/memos_prod.db.bak2 ~/.memos/memos_prod.db

docker run -d
-p 5231:5230
-v memos_data:/var/opt/memos
--name memos
neosmemo/memos:stable

Result was not successful inspite having db data at most 2793472 Bytes in the server.

Please give suggestion or hint to recove the backup data.
