Imagine this: you wake up one morning, open your app, and something's wrong. Your database is gone. Your files are corrupted. Or a simple bug deleted everything clean.
You breathe a little easier because you have backups, right? Except… when you try to restore them, they don't work.
They're empty. Or the format is broken. Or restoring takes forever.
That's the painful truth I learned recently:
A backup is worthless until you've restored it.
My Wake-Up Call
Last month, I was refactoring my side project's database schema.
Something went wrong during migration, and I corrupted my SQLite database.
No problem, I thought, I will just restore my weekly backup.
But when I tried, the backup file was also corrupted.
Later I found out I had been copying the database while the app was still running, catching it middle of writing.
So my “backup system” was creating broken files for weeks, and I didn’t know because I never tested restoring one.
I was lucky it was only dev data, but it scared me.
If that had been production?
If that had been production, I could have lost real users’ data, their work, and my project’s reputation.
What I Learned About Backups While Building Side Projects
Before this, I thought backups were just a checklist: make a copy, sleep peacefully.
But a backup is not magic protection.
It’s just a copy of important things:
- 🧠 Your codebase - GitHub or GitLab usually handle this
- 🗄️ Your database - Postgres, MySQL, Supabase, Firebase, SQLite…
- 🖼️ User files - images, uploads, documents
- 🔐 Configs & secrets - the
.envfile, API keys, deployment settings
The real problem:
You don't know if those backups are good until you test restoring them.
Otherwise, it’s like having an emergency plan locked in a drawer.
How Bigger Teams Handle It
I checked how bigger companies do backups.
GitLab, for example, runs restore tests every day and tracks success rates.
Basecamp even does “disaster tests,” pretending their main datacenter disappears.
Usually, their process looks like this:
- Make backups automatically (nightly dumps, snapshots, etc)
- Restore them into a test environment (not production)
- Check if everything works: database starts, files open, users can log in
- Get alerts when something fails
- Simulate disasters to see how fast they can recover Then I realized: I don't need a datacenter, just a smaller version that fits my side project setup.
And actually, many platforms like Supabase, Neon, and Vercel Postgres now have point-in-time recovery (PITR) built in. Sometimes even free. So before you create your own backup scripts, check your dashboard first.
🧠 What to Back Up
| Type | Backup Method | Test Method |
|---|---|---|
| Code | Push to GitHub/GitLab (with 2FA!) | Clone repo to a fresh folder: git clone <repo> test-restore && cd test-restore && npm install && npm run dev
|
| Database | • SQLite: sqlite3 mydb.db ".backup backup.db"• Postgres: pg_dump mydb > backup.sql• Managed DBs: Use built-in exports or PITR |
Restore to test DB: sqlite3 test.db < backup.sql then run a query to verify data. For Supabase/Neon, use their one-click export + local restore. |
| User Files | Store in Backblaze B2, S3, or Google Cloud Storage (all offer free tiers). Avoid consumer Dropbox for production data. | Download 3–5 random files monthly and verify they open. Bonus: enable object lock or versioning to prevent accidental deletion. |
| Configs & Secrets | Store in a password manager (1Password, Bitwarden) or encrypted offline vault (VeraCrypt). Never in Git—even private repos! | Run project locally using only saved configs. Use GitHub Secrets or .env.vault for CI/CD, not raw .env files. |
⚠️ Important SQLite Tip:
** Copying a live .db file can damage it. Use .backup or VACUUM INTO:
sqlite3 mydb.db "VACUUM INTO backup.db"
This creates a clean, safe copy even while your app is running.
💡 Pro tip: Automate your test restore with a small script:
For example:
#!/bin/bash
set -e # Exit on any error
rm -f test.db
sqlite3 test.db ".read latest_backup.sql"
sqlite3 test.db "SELECT count(*) FROM users;"
echo "✅ Restore test passed!"
You can even run it weekly on GitHub Actions, if it fails, you’ll get an alert.
⏰ When to Test
Monthly (15–30 minutes)
- Restore one random backup locally
- Download a few random user files
- Write down anything strange or failed
Quarterly (1–2 hours)
- Full local restore: DB + files + app
- Time it - how long does recovery take?
- Update your notes
Yearly (half day)
- Pretend your laptop died
- Can you restore everything from your backups and docs?
- It’s a great test for your memory and process.
⚠️ Privacy reminder:
If your app stores user data, make sure backups are encrypted at rest.
Most cloud providers do this by default.
And never keep plain emails or passwords in backups.
Why It Matters
It’s easy to think backups are only for big companies.
But if you're building side projects or working solo, losing data can kill your project one day. Users won’t wait while you say, “Oops, I thought I had backups.”
Now, backups aren’t about peace of mind when I make them;
They’re about peace of mind when I restore them.
Because backups aren’t about paranoia, they’re about love for your future self. ❤️
Well, it is never easy opening up to people about loss from scam either by funds or digital/crypto currency, I decided to personally share my recovery story here to aid in someone’s recovery and wellness. I had an experienced earlier on this year after a failed online investment with the sum of $29,000 on the line.
