Backup ke liye hamaray paas kya kya options hain?
1. CD
2. USB flash drive
3. DVD

Agar Data thora hai aur 700 MB ki range mai hai phir to CD par bhi write kiya jaa sakta hai, is k liye aap k computer mai CD writer ka hona zaroori hai. Blank CD aap ko 10 Rupees tak available hoti hai, aur CD writer 1000-1200 ki range mai used mil jata hai.

Agar Data thora zyada hai to phir USB flash drive mai copy kiya jaa sakta hai, aaj kal 4GB flash drives kafi asani se mil jati hain aur kafi sasti bhi like 650-750 Rupees ki range mai.

Agar data buhat zyada hai, ya aap movies aur songs bhi save karna chahtay hain, yaa aap ki apni family videos bhi hain, aur data ka size GB's mai hai, to phir DVD ki option sab se achi hai.
Aik DVD mai 4 GB tak space hoti hai, aur is k liye DVD writer ka hona zaroori hai aap k computer mai, DVD writer 3200 ki range mai new mil jata hai aaj kal. Blank DVD 20 Rupees tak mil jati hai, jitna zyada data ho utni blank DVD's aap ki consume hon gi.

Agar poori tarah samajh nahi aye, tell me, I will tell you in more detail.
