These two log files in particular are taking 80+ gigs. The databases themselves are really small in comparison. How do I get these to shrink? I've done all I know to do. I performed a full backup of each database, which as I understand it should trigger SQL to reduce the log files. I've gone into Management Studio and on each database, Tasks -> Shrink -> Files -> Log. It'll reduce it by a couple gigs, but then usually goes right back up.
I'm also not sure what all those "aggregation" files in the screen shot are. I don't remember those always being there.
