How should business data be backed up?
If a computer broke or an account locked, what would you lose? The customer list, quotes, accounting files, product photos. Most businesses learn the value of backups after the first loss. 💾
A backup isn’t just a technical job; it is the insurance on knowledge the business built up over years.
Short answer: back up important data using three copies, two different media, one of them elsewhere, and test restoring regularly. An untested backup is not a backup. 🧭
What to back up
BU BÖLÜMÜN ÖZETİ
- Customer and sales data
- Financial records
- Documents
- Website and content
Four groups. 📋
Customer and sales data
Master list, CRM, order records; the most valuable data. 📇
Financial records
Accounting files and invoices; they carry legal duties too. 🧾
Documents
Quotes, contracts, templates; see the documents guide. 📁
Website and content
Site files, database, product photos; expensive to recreate. 🌐
The 3-2-1 rule
BU BÖLÜMÜN ÖZETİ
- Three copies
- Two different media
- One elsewhere
- Automatic
Four parts. 🔢
Three copies
The original and two backups; one copy is no copy. 3️⃣
Two different media
E.g. cloud and an external drive; one fault doesn’t hit both. 2️⃣
One elsewhere
Fire, theft, flood; one copy away from the office. 1️⃣
Automatic
Manual backups get forgotten; scheduled ones run. ⚙️
Are cloud tools backups?
BU BÖLÜMÜN ÖZETİ
- Sync is not backup
- Version history helps
- Accounts can lock
- Exports
Four distinctions. ☁️
Sync is not backup
A deleted file is deleted everywhere it syncs. 🔄
Version history helps
It lets you go back a while; but it is limited. 🕰️
Accounts can lock
Data tied to one account becomes inaccessible if the account has problems. 🔐
Exports
Regular exports from key tools; see the CRM guide. 📤
Restore testing
BU BÖLÜMÜN ÖZETİ
- A test every three months
- Measure the time
- An owner
- Keep a log
Four habits. 🧪
A test every three months
Restore a file from backup; does it work? 🔁
Measure the time
How long does a full restore take? How long does work stop? ⏱️
An owner
The backup has an owner; handed over on departure. 👤
Keep a log
What was tested when, and the result; one line. 📝
Four common mistakes
BU BÖLÜMÜN ÖZETİ
- Backup in the same place
- Never testing
- Password with one person
- Forgetting the website
All four make backups useless. 🚧
Backup in the same place
Laptop and external drive in the same bag; both lost together. 🎒
Never testing
A broken backup is discovered when you need it. 😱
Password with one person
If nobody knows the backup password, it can’t be opened. 🔑
Forgetting the website
Site backups are left to the host; you should have your own copy. 🌐

Three steps, one hour. 🪜
Step 1: list critical data
The four groups whose loss would stop work; where do they live? 📋
Step 2: check 3-2-1
How many copies, how many media, one elsewhere? Which is missing? 🔢
Step 3: try a restore
Restore one file from backup; today. 🔁

📝 Notes From the Field
A business’s accounting files lived on one computer and an external drive on the same desk; a water leak damaged both. After partial recovery, a 3-2-1 routine was set up: cloud, external drive and an off-site copy, on a schedule, with a restore test every three months. At the next hardware failure, work resumed within a few hours.
📖 Short Glossary
Backup: a copy of data that can be restored after loss. 3-2-1 rule: three copies, two media, one elsewhere. Sync: keeping files identical across devices. Restore: bringing data back from a backup.
⚡ Quick Summary
A backup is insurance on the knowledge a business builds. 💾 Back up customer, financial, document and website data. Apply 3-2-1: three copies, two media, one elsewhere, running automatically. Sync is not backup. Test restores every three months; an untested backup doesn’t count.
