guide
Spill coffee on your laptop today and you should lose nothing. Here's how to set up automatic, off-site backups for free — not by learning to code, but by telling an AI assistant to do it for you. About twenty minutes once, then you never think about it again.
June 17, 2026 20 minute setup backups
A friend of mine spilled a glass of water on her laptop last night. Keys stopped working. She spent the next hour frantically dragging files into iCloud, hoping she'd grabbed the important ones before the machine died.
She hadn't done backups. Almost nobody has — not because they're careless, but because every backup tutorial assumes you enjoy reading about "cron jobs" and "S3 buckets." You don't. You just don't want to lose your photos.
Here's the thing that's changed: you no longer have to understand any of that. You can install a free AI assistant that lives in your computer's terminal, tell it "set up automatic backups of my important folders to free cloud storage," and it does the technical part — installs the tools, writes the config, schedules it to run every day. You stay in plain English the whole time.
This guide walks you through it once. Be honest with yourself about the time: it's roughly twenty-five minutes of one-time setup, and a few of those minutes are clicking through a couple of free signups. After that, it runs itself forever and you can forget it exists.
What this costs
The honest catch: 10 GB of free storage is plenty for documents and the photos you'd cry over, but it is not enough to back up your entire computer. That's fine — most of what's on a computer (apps, system files, downloads you could grab again) doesn't need backing up. Step 3 is about picking the stuff that actually matters, and your AI helper does the picking with you.

This all happens in the Terminal, a plain text window where you type instructions to your computer. Don't worry, you'll only paste a couple of lines.
You now have an AI assistant running in your terminal. Everything from here is just talking to it.
Your backups need somewhere to live. We'll use Cloudflare R2: 10 GB free, and — unlike most cloud storage — free to pull your data back out. This is the one part the AI can't do for you, because it involves creating an account. About 10 minutes.
my-backups. Leave the defaults. Create it.https://abc123.r2.cloudflarestorage.com).Copy all three somewhere safe right now. Cloudflare shows the Secret Access Key once and never again. Treat these like a password — they only grant access to this one storage bucket, and you can delete the token in Cloudflare anytime to cut off access instantly.
Keep that window open. You'll paste those three values to your AI in Step 4.
This is the step that keeps you inside the free 10 GB and stops you from backing up three copies of the same vacation album. You're not going to guess — you're going to ask your assistant to look and advise.
Make sure your AI assistant is running (you typed and it's waiting for you). Paste this:
I want to set up automatic backups to a free cloud bucket that holds up to 10 GB. Before changing anything, look through my home folder and tell me: (1) my biggest folders and files, (2) any obvious duplicate photos or files I could skip, and (3) which folders hold things I'd be devastated to lose — like documents and photos — versus things I could just re-download later, like apps, caches, and downloads. Then suggest a specific list of folders that fits comfortably under 10 GB. Explain what you find before doing anything.Your assistant will look around and come back with something like "Your Photos folder is 40 GB — too big for the free tier, but your Documents (2 GB), Desktop (1 GB), and your 'Favorite Photos' album (3 GB) fit easily. I found ~800 duplicate images in Downloads we can ignore." Talk to it. Tell it what matters. You end Step 3 with a short list of folders worth protecting — chosen by you, surfaced by the AI.
The goal isn't to back up everything. It's to back up the things that, if the water wins tonight, you'd be heartbroken to lose — and nothing else. — the whole point of this guide
Now the magic part. Paste this prompt, filling in the bracketed bits with the folder list from Step 3 and the three values from Step 2:
Set up automatic daily backups of these folders — [paste your folder list] — to my Cloudflare R2 bucket, using a tool called rclone. Here are my R2 details:
- bucket name: [your bucket name]
- account ID: [your account ID]
- access key ID: [your access key]
- secret access key: [your secret]
- endpoint: https://[your account ID].r2.cloudflarestorage.com
Please do this step by step, explaining each part in plain English before you run it:
1. Install rclone if it isn't already, and configure an R2 remote (provider Cloudflare, and add no_check_bucket = true).
2. Store my access key and secret securely — in a file only my account can read (lock the file permissions), and never in plaintext anywhere that syncs to the cloud. Tell me where you put them and why that's safe.
3. Run one small test upload so we can confirm it works.
4. Schedule the full backup to run once a day — but don't assume my computer is awake at a fixed time. Set it up so that if the machine was asleep or off at the scheduled time, the backup still runs as soon as it's next awake, and briefly wake the computer to run it if my system supports that. Use whatever my OS's built-in scheduler does best for this.
5. Set up a free "dead man's switch" alert so I'm warned if a backup ever fails or silently stops running: walk me through making a free account at healthchecks.io, then have my daily backup ping its URL only when it finishes successfully — so I get an email if it ever goes quiet, not just if it errors.
At the end, tell me how I'd follow up if I ever get a failure alert.Your assistant will narrate as it goes — installing rclone, writing the config, running a test, setting up the daily schedule, and wiring up your failure alert. When the test upload works and the alert is connected, you're done.
The "explain before you run it" line matters. You're letting an AI run commands on your computer, so make it show its work. If it ever proposes something you don't understand, ask "what does that do and is it safe?" before you say yes. A good assistant will happily explain. This habit — make it narrate, then approve — is how you stay in control.
Three things that prompt set up — and why they matter
If that alert ever arrives, don't panic — open your AI assistant and paste: "my R2 backup stopped checking in, figure out why and fix it." It can read the logs, find the cause (often something simple, like a folder that got renamed), and get you running again.
Don't take "done" on faith. Ask:
Show me that the backup ran: list what's currently in my R2 bucket, and remind me how the daily schedule is set up and how I'd check next week that it's still running.You should see your files listed in the bucket. You can also log into cloudflare.com → R2 → your bucket and see them sitting there. That's proof. From now on it runs every day on its own.
Bottom Line
Twenty minutes, zero dollars (if you want it to be), and zero code written by you. The next time water meets laptop, the laptop is the only thing you lose.
This is the small, boring superpower of a terminal AI assistant: you describe the outcome you want in plain English, and it handles the machinery. Backups are just the first thing worth pointing it at.
More guides coming. This is the first of a series on getting an AI assistant to do the useful, slightly-technical chores you've been avoiding.
