Cloud service providers, such as those providing BaaS (Backup as a Service), must ensure that their data is stored in data centres that adhere to extremely strict standards of security and protection. Accordingly, compared to organisations that store their data on a central server of a regular office, data is likely to be much safer with BaaS than in a typical office that doesn’t necessarily maintain such strict security protocols.
Additionally, and a major factor for why data is safer with cloud backups, if you experience a hardware failure, where traditional backups are stored, there’s a severe risk of losing all your backed up data entirely. There can be any multitude of causes that might bring about either deliberate or accidental damage to hardware. The risks are certainly reduced in the cloud, which can store your data across multiple sites to spread any risk of loss.
In some rare circumstances however, there may be practical reasons for why an organisation might choose traditional backups over the cloud. For instance, in the case of some ransomware attacks, it might be possible for certain traditional backup providers to provide instant recovery in the case of systemwide failure. So, if the prospect of downtime in your company is a terrifying one, this might be something to consider.
Also, some organisations may have very specific data security requirements that stipulates their data must be stored on maximum security personal premises. In this case, it might either be unfeasible or too expensive to switch to cloud backups.
Ultimately, you can generally assume cloud backups to be very safe however, the specific circumstances of individual organisations vary, and accordingly one size does not fit all. Speak to your IT professional if you want guidance on this topic.
