Sure but if the file is archived every day, the current one won't ever get
huge.  And you don't need to make multiple backups of those already
archived.

You surprise me.  You use every app every day?  The reason to keep lots of
logs is to give you a good chance that you still have a log from when
something was last used ok - which could be weeks or months ago.

Even in normal use if you're ill or on holiday your machine might not get
used for a few weeks.  You don't want the first thing that happens when it's
next booted is that all the old logs are deleted.

It's too much like hard work using per-app log managers.  It's far easier to
use your own code to move any app's log to an archive and (if necessary)
place an empty log file where the app can then add to it.
