One person’s “paranoia” is another person’s “engineering redundancy.” — Marcus J. Ranum
March 31st was World Backup Day, so this week I wanted to talk about backups.
With the amount of information we store on our computers and phones, and the cost of storage, how can we not consider having a good backup system in place. Think about what you store from precious family photos, financial information, software and art we create, documents we write, and so many other things. What would you do if your drive failed? Would you be able to recover those precious documents? What if your computer was stolen?
It is suggested to have more than one copy on more than one type of media. For recovery speed and ease, an external drive connected to your machine is a good start. Consider fire, flood, and theft, and you would be wise to consider an off-site solution (I use CrashPlan). To be truly safe and not to trust a third party, you might consider storing something in a safe deposit box or at a trusted location.
For my most important data, I have a copy on my computer, a copy on mirrored external drives, a copy with CrashPlan, and a copy with a trusted acquaintance in their safe. All copies are encrypted before being sent and I hold the key.
