Suitable Device That Needs to be Backed up
Answer should be Cloud Storage. (not 100% sure, please check explanation)
To backup bulk data we need an external hard disk of bigger size or cloud storage.
Data capacity of given devices:
- 32 GB USB stick – fix 32 GB approx
- 500 GB Portable HD – fix 500 GB approx
- RW-CD – fix 700 MB approx
- Cloud Storage – variable size,
Cloud Storage can be used to store small to very large data. They can store files of as small as a Byte to Thousand of Terabytes.
32GB USB stick and RW-CD is of lower capacity than our need. We can either use 500 GB Hard Disk or Cloud Storage.
But for optimal condition we should use Cloud Storage service to backup 150 GB data securely. In this way their will be not wastage of space on 500 GB HD.
