'Use Multi-Factor Authentication'

What Is Multi-Factor Authentication (MFA)?

MFA is an authentication method that requires more than one method to verify the authenticity of the users to provide access to the system, network, or any resource.

Physical Backups Physical backup is a traditional method to store a copy of your data to a local disk, network drive, or external hard drive. It provides more control over the data and easy recovery in case of data loss. Physical backups could be damaged in case of a natural disaster, so it is always better to have physical and remote backups.

Cloud Backups Cloud backup is a kind of remote backup, where you store a copy of the business or private data in a cloud server. There are many public cloud providers in the market who offer cloud backup services. Also, big organizations may have their own cloud backup systems. As many small companies have started using cloud services, cloud backup is getting even more popular.
