宝塔7.6网站备份，排除规则出现重复不过修改

把

    #构造排除
    def get_exclude(self,exclude = []):
        if not exclude:
            tmp_exclude = os.getenv('BT_EXCLUDE')
            if tmp_exclude:
                exclude = tmp_exclude.split(',')
        if not exclude: return ""
        for ex in exclude:
            self._exclude += " --exclude=\"" + ex + "\""
        self._exclude += " "
        return self._exclude

换成

    # 构造排除
    def get_exclude(self, exclude=[]):
        self._exclude = ""
        if not exclude:
            tmp_exclude = os.getenv('BT_EXCLUDE')
            if tmp_exclude:
                exclude = tmp_exclude.split(',')
        if not exclude: return ""
        for ex in exclude:
            if ex[-1] == '/': ex = ex[:-1]
            self._exclude += " --exclude=\"" + ex + "\""
        self._exclude += " "
        return self._exclude
