Backup a 130 MB files is a computer intensive process. I use BackUpWordPress to schedule database only backup. For files backup I do it manually using cPanel's File Manager once a month.
Backup (or compressing) large files using File Manager is far better and faster (I think). I regularly backup a single site that have size of about 60 MB and sometimes multiples sites into a single 150+ MB file without any problem using File Manager.
Many webhost limit the script max. runtime. But I think it will be more tolerable if you're using cPanel File Manager.
