I am new to everything WordPress! Needed a backup solution and found Total Upkeep. Just installed and activated the FREE version. I market to a rather limited pool of customers and self-host on a NAS. Yes, my website is slow at times. Just getting started. Anyway, going through the settings for Total Upkeep I came across the Available Compressors. Took a screenshot for you. Just wondering if this is an issue I need to deal with, or should the plug-in still be able to make a valid backup? Under system zip it says ‘unable to restore all files and folders’.
Any advice would be appreciated.
