I’ve always felt about backups the same way I do about insurance policies. That cocky voice inside my head says, “What, me worry? It’ll never happen to me.” But as they say, it’s not if, it’s when. Disaster always strikes, and for the unprepared, it can be catastrophic: loss of intellectual property, precious memories, time, and sometimes even an entire business. So, if your backup strategy extends no further than hope, heed my words and take action now. It isn’t that difficult, and someday you’ll pat yourself on the back for planning to survive what could have been your worst day.

What to Backup: The Art of Digital Hoarding (With Purpose)

Not so long ago, we had to be judicious about what we chose to backup. Backing up even gigabits of data was costly and time-consuming. Now, with terabytes at our fingertips or just a high-speed connection away in the cloud, why not backup everything?

Well, that’s a lazy approach. Despite cheaper storage and faster networks, if you like to keep backups for a long time, this can get uncomfortable, if not expensive, even now.

I focus on backing up anything I created, or that my system created to document activity, that can’t be easily recreated or replaced. This includes:

• Documents, photos, and videos (the obvious stuff)
• Configuration files
• Customized templates
• Logs tied to the operation of your applications and devices

Applications you can easily reinstall probably don’t need the same backup treatment. But beware, this can get complicated:

• Certain file types, if open when a backup runs, won’t be restorable later.
• Local relational databases require special care.
• Some video codecs are unplayable without the completed file.

When to Backup: Timing is Everything

Once you’ve figured out what needs backing up, consider how frequently that data changes. This should drive your backup frequency. If your critical files change constantly, you might need near real-time backups. For less volatile data, daily, weekly, or monthly backups might suffice.

It’s all about balancing pain now (time and performance impacts) against potential pain later. If losing a day’s work is acceptable, daily backups might be enough. But you’re the judge – no one knows your tolerance for data loss better than you do.

How I Roll: Confessions of a Backup Paranoid

I don’t much like insurance; it’s a necessary evil. But I’ve been burned before by inadequate backup strategies, so now I err on the side of paranoia.

Here’s a peek into my backup madness:

1. Full Disk Images: I capture these periodically for bare-metal restoration if disaster strikes. Frequency depends on how often the system changes:

• Regularly changing systems: Quarterly
• Static systems: Semi-annually

2. Tiered Backups: For documents and logs, I use a tiered approach:

• Hourly snapshots (retained for 24 hours)
• Daily backups (retained for 1 month)
• Weekly backups (retained for 3 months)
• Monthly backups (retained for 1 year)
• Quarterly backups (retained indefinitely)

3. Local and Cloud Storage: Everything gets backed up locally first, then synced to encrypted cloud storage for redundancy. Because losing your backups to the same disaster that took out your original data? That’s a special kind of pain.
4. Revision Control: For configuration files and other frequently changing documents, I’ve found utility in using revision control systems like Git. It’s like Time Machine for your code and configs!

Software Makes It All Easier (But Don’t Get Lazy)

If you’re on a Mac, Apple’s Time Machine is a no-brainer. Grab a cheap 4TB external drive, encrypt it, and let Time Machine do its magic. It’s like a…ummm…time machine…for your data.

For Windows users (or cross-platform folks like me), I’ve been relying on Arq for about three years now. It handles local and cloud backups simultaneously and has saved my bacon more than once during hardware failures on my gaming PC.

Linux users, I see you. While I could bore you with my backup scripts involving cron, bash, rsync, and friends, I’ll spare you the details. Just know that the same principles apply, even if the tools differ.

Restore, Restore, and Restore Again: The Forgotten Step

Here’s where many people drop the ball: they back up diligently but never test restoration. It’s like having a parachute you’ve never opened – you hope it works, but you’re not sure.

Schedule time, at least annually, to test your restoration procedures. It’s not just for business continuity compliance – it’s peace of mind. Trust me, you don’t want to compound one disaster with another by discovering your backups are useless when you need them most.

Final Thoughts: Backup or Back Off

Remember, most of what I’ve discussed applies to personal devices – from work laptops to gaming rigs. Server infrastructure often has its own specialized needs and tools.

Now, if you’ll excuse me, I need to back all this up before I take a coffee break! Because in the world of data, you never know when disaster might strike. Stay safe out there, my fellow digital hoarders!
