Backup and recovery is the process of duplicating data and storing it in a secure place in case of loss or damage, and then restoring that data to a location — the original one or a safe alternative — so it can be again used in operations. Ideally, this backup copy (often called a snapshot) is immutable —meaning it cannot be altered after it is created to protect against mutations such as ransomware. Backup and recovery is also a category of onsite and cloud-based technology solutions that automate and support this process, enabling organizations to protect and retain their data for business and compliance reasons.

IT security is the protection of information and especially the processing of information. IT security is intended to prevent the manipulation of data and systems by unauthorized third parties.
