What is data backup and recovery?
Data backup and disaster recovery are often conflated or used interchangeably.
However, each involves different practices and deployment technologies, so
differentiating them is critical when developing comprehensive strategies.

Data backup involves replicating or creating multiple copies of data and storing them
in a location different from the source. This is done to restore and protect
sensitive data in the event of accidental deletion, database corruption, security
breach or technical catastrophe. Data backups come in several forms, from creating
alternate storage means and remote data centres like the Cloud to host the
duplicated data to creating copies to store in secondary storage arrays.
On the other hand, Disaster Recovery is the complete process involving strategies
tailored towards retrieving lost or damaged data to its original state. Effective
Disaster Recovery operations safeguard and restore data during downtime or outage.
It reestablishes access to files, applications, IT resources, etc. Such operations
could involve creating a redundant storage system as a secondary location to host
all sensitive resources the enterprise needs to function. It could also involve
switching from your primary data centre when it’s down to another server until the
primary location is functional again.
