Cloud Backup Setup — 3-2-1 Backup Strategy Guide (2026)

1. 3-2-1 rule kya hai

3 copies of data, 2 different media (HDD + cloud), 1 offsite. Ransomware attack me sirf offsite backup aapko bachata hai.

2. Google Drive backup

Google Drive Desktop install → sync folder select. 15 GB free, Rs.130/month for 100 GB, Rs.650/month for 2 TB. Version history 30 din.

3. OneDrive backup

Microsoft 365 subscription (Rs.489/month) ke saath 1 TB per user. Business plans me 5 TB tak. Ransomware detection built-in.

4. Amazon S3 — professional

Advanced users ke liye — highly reliable, cheap Rs.2/GB/month. Bade data (>2 TB) ya compliance requirement ke liye best. Backup software (Duplicati, Restic) se automate.

5. What to backup

Documents, photos, project files, database dumps, email PST, browser bookmarks. OS aur programs backup mat karo (reinstall easy hai).

6. Encryption

Cloud pe upload hone se pehle client-side encryption (Cryptomator, Boxcryptor). Provider bhi aapki files padh nahi sakti.

7. Scheduling

Real-time sync (Drive/OneDrive) OR daily incremental (Duplicati). Business data ke liye daily minimum, hourly ideal.

8. Restore test

Backup successful hai ye maano mat — mahine me ek baar random file restore test karo. Untested backup = no backup.
