I never walked into a business without discovering gaping holes in their backup and recovery systems. When an independent business person recently told me their story of woe of losing gigs of files, I pulled this picture up on my phone. While cumbersome and old school, it is my only guarantee that I will not lose any data. For less than a thousand dollars I have multiple backups of ALL my files. These drives stay mostly unplugged, as it extends their life before failure. These drives will fail, but that is why I have multiple. There are much better ways to recover than this, and I fully endorse and implement those technologies. Reach out to me for help. My initial consultation is free.
