Storage and Backup in RDS
Because even your database needs a safety net!
Welcome back, noob developer! 👋
Now that you’ve got your shiny RDS instance up and running, let’s talk about what keeps it safe, secure, and speedy — storage and backups!
Because let’s face it — one accidental DROP DATABASE command and your day’s gone from ☀️ to 🌧️ real quick.
💾 Storage Types: Choose Your Power-Up
RDS offers different types of storage — kinda like picking your ride in a racing game 🏎️
🚗 General Purpose SSD (gp2/gp3)
- Your default all-rounder storage.
- Great balance of cost and performance.
- Ideal for most workloads — from hobby projects to small apps.
- Think of it as your “Maruti Swift” — reliable and economical.
🏎️ Provisioned IOPS (io1/io2)
- Built for high-performance, mission-critical databases.
- You can manually set IOPS (Input/Output Operations Per Second).
- Perfect for production-level apps that handle thousands of transactions per second.
- Basically the Lamborghini of storage types — fast, but expensive 💸.
🚲 Magnetic (Standard)
- The old-school option — like using a floppy disk in 2025.
- Slower and cheaper, mostly here for backward compatibility.
- Don’t use it unless you’re feeling nostalgic.
⏰ Automatic Backups and Snapshots
RDS has your back (literally). It automatically takes backups of your database every day.
So even if you mess up — AWS whispers, “Don’t worry, I got you.” 💪
🪄 Automatic Backups
- Enabled by default! (thank you, AWS 🙏)
- Lets you restore your DB to any point in time within the retention period.
- Default retention: 7 days (can increase to 35 days).
💡 Pro tip: Think of this as an Undo button for your database.
📸 Snapshots
- Manual backups you create yourself.
- They stick around until you delete them.
- Perfect for “before major updates” moments.
- Example:
“About to run a migration? Better take a snapshot first, buddy.”
🔄 Restoring from Backup
Did you just nuke your database by accident?
No worries, we’ve all been there 😭
Here’s how to bring it back from the ashes:
- Go to RDS Dashboard → Snapshots
- Select a snapshot → Click Restore snapshot
- AWS spins up a new RDS instance with the same data
- You connect to the new one and pretend nothing ever happened 😉
🧍🧍 Multi-AZ Deployment: RDS with a Twin
Imagine if your database had a twin living in another city, ready to take over if the first one catches a cold 🤧
That’s Multi-AZ Deployment.
- RDS automatically maintains a standby replica in another Availability Zone.
- If the main one fails, the replica takes over instantly.
- Zero data loss. Zero downtime.
- Basically, your DB just got itself a backup bodyguard 🕶️
💬 Think of it like:
“Main DB down? No problem. Backup DB reporting for duty, sir!”
🏁 TL;DR
