Backing up data on my multiple Linux computers has always been a gray area for me. The process of backing up data for me boiled down to convenience and cockiness. I thought my no-app backup procedure was a better option. That twisted view nearly resulted in a data disaster for me recently. Having multiple computers all storing the same data tends to make reliance on an actual backup application seem to be a needless redundancy. But a round of system failures put my access to backup data at risk.
