1.1.13 Describe a range of methods that can be used to prevent data loss

Methods that are used to prevent data loss include failover systems, redundancy, removable media, offsite/online storages.

Failover Systems
- Data is also stored in an extra system (hardware, software, network) which starts working once an error is detected in the main system.

Redundancy
-The same data is stored in different places
-Example: RAID- Redundant Array of Independent Disks. It has differewnt levels, each with different methods of storing data.

Removable Media
- This includes external harddrives, disks, USB

Offsite Storage
- Local storage that does not require internet.

Online Storage
-For eaxample Clouds. They require internet
