I was recently reviewing the computer backup system that I have in my office, and I started to get worried. All of my office's important data is contained on a network drive that everyone can access. This drive is then backed up, every night, to another drive. My thought process back then was that if a drive failed one day, I still had a copy of its data from the day before!
While this idea still holds true for drive failure problems, I realized I was unprepared for a 'human error' type problem. Let's say someone in my office accidentally deleted a key folder, and didn't notice until a week later. Because I only have backups for the past day, it would be missing forever!
To solve this problem, I have added another set of backups to my routine: weekly backups. Once a week, my network folder is now set up to back up to an external drive. Instead of replacing this backup every week, I am KEEPING all the weekly backups, at least for a month or so. This way, I can go back a few weeks to fix any human errors that may arise. This is in addition to the daily backup, which I'm still keeping going.
What does everyone think? Are you prepared for digital and human errors with your backup system?
