I’m not sure what re-spinning a container means. The first time I placed phpbb_mysql.sql in the mysql directory per these instructions. Is there more to do than that?
The attachments you can just copy over.
Yeah. ‘cept, the tar.gz is 15GB because there’s 45GB of data in the phpBB /files directory. I have been running my board for 22 years, doncha know! So yes, I’ll copy them back. But likely, it will be tomorrow before I pick this up again.
