We've added: /bin/nice -n $backup_nice (FreeBSD and Debian will use /usr/bin/nice) before all tar, zip, and unzip commands. This includes, backup, restores, skins, and Filemanager compression/extraction. This assumes you have "nice" in the above location for your OS. If you don't, you will need to add it, as tar, zip/unzip will throw errors if it's missing. No action is required. This is enabled by default for everyone.
