  1. Awesome Article! I’ve been very impressed with your articles so far. I know it has been a few weeks since you originally posted this, but I haven’t had time to comment. I have a question I’ve been trying to find the answer for and I was hoping you might have some insight. I’m considering investing in backupbuddy or updraftplus. They are similarly priced, but I can’t see a clear winner. Any insight would be greatly appreciated! Also, I’ve heard some criticize anything back-up plugins besides vaultpress because theoretically a hacker could just mess with your plugin once they are in your site. I’m still leaning towards backupbuddy or updraftplus for the economic advantages.

  2. First of all thank you for posting. The plugin I am looking for is the one you are having on your website. Could you please let me know what plugin are you using.???

    • One of my clients websites was infected by malware delivered by Sweet Captcha. She lost a few potential clients (who thankfully told her about the malware popups) and narrowly escaped being blacklisted by Google. Since she heavily relies on great Google positions this could have totally destroyed her business.
