Keep getting warnings about file names

Hello, I keep getting warnings about the length of file names when running BackWPup, either manually ir through wp cron

WARNING: File name "wp-content/cache/minify/...gzip" too long to be saved correctly in TarGz archive!
(file name truncated for this topic)

Since these are cache files, there is no real need to preserve them.
Is there a way to avoid backing up specific folders or files?
