You can use the *maxBytes* and *backupCount* values to allow the file to
:dfn:`rollover` at a predetermined size. When the size is about to be exceeded,
the file is closed and a new file is silently opened for output. Rollover occurs
- whenever the current log file is nearly *maxBytes* in length; if *maxBytes* is
- zero, rollover never occurs. If *backupCount* is non-zero, the system will save
- old log files by appending the extensions '.1', '.2' etc., to the filename. For
- example, with a *backupCount* of 5 and a base file name of :file:`app.log`, you
- would get :file:`app.log`, :file:`app.log.1`, :file:`app.log.2`, up to
- :file:`app.log.5`. The file being written to is always :file:`app.log`. When
- this file is filled, it is closed and renamed to :file:`app.log.1`, and if files
- :file:`app.log.1`, :file:`app.log.2`, etc. exist, then they are renamed to
- :file:`app.log.2`, :file:`app.log.3` etc. respectively.
