What is a data storage solution for backing up data?

edit

There are several data storage solutions for backing up data, some of which include:

1. External hard drives: These are portable hard drives that can be plugged into a computer to save and store data.

2. Cloud storage: Cloud storage services such as Google Drive, Dropbox, and OneDrive allow users to store data in the cloud and access it from anywhere with an internet connection.

3. Network Attached Storage (NAS): A NAS device is a centralized data storage solution that can be accessed by multiple devices on a network.

4. Tape backup: Tape backup involves storing data on magnetic tapes, which are then stored offsite for disaster recovery purposes.

5. Optical storage: Optical storage devices such as CDs, DVDs, and Blu-ray discs can also be used to store and backup data.
