Phone paani mein gir gaya, laptop chori ho gaya, ya virus ne sab kuch lock kar diya — aisi ek ghatna saalon ki yaadein (photos, videos, documents) mita sakti hai. 3-2-1 backup rule duniya bhar ke experts ka sabse bharosemand formula hai taake aapki koi file kabhi na khoye.
3-2-1 Ka Matlab Kya Hai?
3 = apne important data ki kam se kam 3 copies rakhein. 2 = in copies ko 2 alag-alag jagah (media) par rakhein, jaise phone + external hard disk. 1 = ek copy ghar se door rakhein — cloud storage ya kisi aur shehar mein. Ek hi jagah rakhi hui 10 copies bhi ek backup nahi — alag jagah hona zaroori hai.
Backup 1: Automatic Cloud Sync
Sabse aasaan shuruaat hai phone ki photos ka auto-backup on karna — Google Photos ya iCloud mein. Ye muft (kuch limit tak) hai aur bina kuch kiye roz backup hota rehta hai. Documents ke liye Google Drive ya OneDrive ka auto-sync kaafi hai. Auto-backup on karna 2 minute ka kaam hai aur sabse bada suraksha jaal hai.
Backup 2: External Hard Disk
Mahine mein ek baar apni zaroori files external hard disk ya pen drive mein copy kar lein. Ye backup internet ke bina kaam aata hai aur ransomware se bhi surakshit rehta hai — bas backup ke baad disk ko computer se alag karke rakhein. Disk hamesha computer se judi rahe to virus use bhi kharab kar sakta hai.
Backup 3: Door Ki Copy
Aag, baadh ya chori mein ghar ki saari cheezein ek saath jaa sakti hain — isliye ek copy cloud mein ya kisi rishtedaar ke ghar rakhi disk mein honi chahiye. Cloud storage aaj bahut sasta hai, aur family plan mein aur bhi kifayati. Door ki copy wo insurance hai jiski zaroorat ummeed hai kabhi na pade.
Backup Test Karna Na Bhoolein
Sabse aam galti hai backup bana kar bhool jaana. 3 mahine mein ek baar check karein ke files waqai khul rahi hain aur nayi photos backup ho rahi hain. Purani disk kharab bhi ho sakti hai. Test na kiya hua backup, backup nahi — sirf ummeed hai.
