simplified high-level description of grooming? - useful for daily updates on AV signatures?

[philx509]

My security software (Norton Internet Security) does daily updates on AV "signature" files, which of course get backed up. But old signature files have no real value, and I woudl like to be able to delete just those files from a backup set. Can grooming help me here?

 

From what I can tell, NIS uses multiple files, in different locations, as part of this daily update process, and the file names are unique, so I can't just exclude these update files by name. If I'm wrong about any of this, I'm entirely open to any approach that solves my problem.

You could try excluding the folder containing these files from the backup by creating a new rule that excludes this folder.
