is there any i can restore a deleted forum from a sql backup?
one of my moderators deleted the contents (all the topics) of a forum, whilst in an inebriated state ...
i do data backups every day, but i don't want to overwrite the posts made since the last backup.
is there any relatively safe way this can be done??

it can be totally safely done, but it's uber sql time..
main problem is the autoincrement issue with POST_ID and TOPIC_ID, but that can be done too..

well my site isn't that large, < 100,000 messages. the deleted forum contained about 5000 posts, so i am guessing it won't take too long. is it a matter of getting the last POST_ID and TOPIC_ID autoincrement values, then appending from the backup POST table to the current POST table, checking each message to see what forum (FORUM_ID in TOPICS table) it was posted to? (as if that wasn't complex enough!)

yah, you perty much have it figured.. only thing i would do is temporarily remove the autoincrements, so it could be a straight transfer over with no math or gyrations involved in ID mapping .. then edit (ALTER) the indices back after done..

I'd restore to a new location, purge everything that doesn't pertain to what you want to restore, sql dump everything to be restored, then restore it to the current db...

gizmo, that's exactly what i did, in fact! i took a copy of the backup database, killed all the extraneous records, then inserted that into the current database. actually, both ubbt_POSTS and ubbt_TOPICS had to be repaired, not just ubbt_POSTS alone.

Well, I coulda told you that  ... It'd be because the topics table hold information on topics; and the posts table holds the post data
