Hello,
I just upgraded from SMF 2.0.19 to SMF 2.1.0 using large upgrade, and selected (by default) the backup of the database. Now I have the useful parts ("smf_fet_admin_info_files, ...) and the non-useful parts ("backup_smf_fet_admin_info_files, ...). What should I do with the "backup_*" tables? I could remove them, or is there a particular automatic option for this, or should I leave them?
I have a backup of the current database, of course.
If you have a backup yourself (not on the server), you can delete them. There is no automated tool for this.
After you have made sure everything is working as it should, you can just remove the backup_ tables.
They are basically only a failsafe measure.
EDIT: I think I'm gonna give up and go to sleep, I'm getting slow :P
Thank you both! :)
