Answer
Using DVDs is possible but inefficient; using a Blu-ray Disc (BD) is more practical, faster, and reliable for this size of data.
Work Step by Step
Yes it would be reasonable to use a DVDs for this backup as the size is around 10 GB . It can easily serve us the purpose but data transfer rate would be a little slow.
Apart from it the blue-ray would be am better option.
The DVD option:
A single-layer DVD holds about 4.7 GB.
A dual-layer DVD holds about 8.5 GB.
To back up 10 GB you’d need 3 single-layer DVDs (since 2 × 4.7 = 9.4 GB < 10 GB) or 2 dual-layer DVDs (since 2 × 8.5 = 17 GB > 10 GB).
Conclusion for DVDs:
It’s possible but not convenient — you’d need multiple discs and more time to burn and manage them. DVDs are better for smaller backups.
The BD (Blue-ray) option:
A single-layer Blu-ray Disc holds 25 GB, a dual-layer Blu-ray Disc holds 50 GB.
Conclusion for BDs:
Using Blu-ray is much more reasonable and efficient. A single 25 GB Blu-ray Disc easily stores the 10 GB backup, offering faster writing speed, higher reliability, and less physical media to handle.
Therefire, using DVDs for a 10 GB backup is possible but inefficient; using a Blu-ray Disc (BD) is more practical, faster, and reliable for this size of data.
