Guide to Backup and Restoration for CompTIA Network+
What is Backup and Restoration?
Backup and Restoration refers to the process of creating copies of data (backup) which can be used to restore the original in case of data loss. This is a critical procedure in network operations to prevent data loss due to issues such as hardware failures, data corruption or cybersecurity incidents.
Why is it important?
Backup and Restoration is important because it allows continuity in the event of data loss. It's vital in reducing downtime and ensuring quick recovery in network operations. Without it, data loss can lead to significant operational, financial, and legal implications.
How it works?
It works in a straightforward manner: Data is copied and stored in another location. This location can be a physical device like tape or virtual like cloud storage. In case of any data loss, the stored data is restored back to its original location.
