Backup is the activity of copying files or databases so that they will be preserved and available in case of equipment
failure or other catastrophes. Backup are of three types namely Local Backup, Off-site Backup, and Cloud Backup

What is Local Backup?
Local Backup: Backing up critical files to diskettes. This approach is commonly used by people who keep their checkbooks and personal finance data on the computer. Programs like Quicken and Managing Your Money always remind users when they quit the program to backup their data. If your hard disk crashes, you’ll be able to reconstruct your checkbook balances. If you have other files (for example, chapters of a book you’re working on), you’ll want to backup every single day’s work. Copying it to a diskette is quick and economical.
What is Off-site Backup?
You can also consider sending your files to another site for safekeeping. In case your hard disk crashes, you’ll be able to download them from the safekeeping site.
What is Cloud Backup?
Cloud backup, also known as online backup, is a strategy for backing up data that involves sending a copy of the data over a proprietary or public network to an off-site server. The server is usually hosted by a third-party service provider, who charges the backup customer a fee based on capacity, bandwidth or number of users. In the enterprise, the off-site server
might be proprietary, but the chargeback method would be similar.
What is Disaster Recovery and High Availability?
Disaster recovery and High Availability is the area of security planning that deals with protecting an organization from the effects of crippling cyber attacks, equipment failures, hurricanes, earthquakes and other natural disasters.
A disaster recovery plan (DRP) documents policies, procedures and actions to limit the disruption to an organization in the wake of a disaster. A disaster recovery plan consists of actions intended to quickly resume mission-critical functions.
In information technology, disaster recovery includes restoring servers or mainframes with backups, reestablishing private branch exchanges (PBX) or provisioning local area networks (LANs) to meet immediate business needs. Because business continuity and disaster recovery are so closely related, the two terms are sometimes combined as Business Continuity and Disaster Recovery (BCDR or BC/DR).
Mail Archiving
A systematic approach to saving and protecting the data contained in e-mail messages to be accessed quickly at a later date. In the past, the IT department backed up e-mail, in a manner that made messages UNSEARCHABLE. If a specific e-mail needed to be traced, it took weeks to find it. With today’s compliance legislation and legal discovery rules, it can be located in minutes, not weeks. The Policy-based e-mail archiving software applications allow IT managers to manage large e-mail archives, free up space on production servers and speed up backup times. These applications include indexing and search capabilities, access logs to provide a “virtual paper trail” when an e-mail is subpoenaed, a lifecycle management component acting as a traffic cop for all e-mail coming in to the company. The life cycle management component uses rules set up by the administrator. It will classify e-mail messages needed to be archived, migrate messages to most economical and efficient storage media, and automatically delete messages when no longer needed.
