Backup is copying files and data from one computer to a second medium, such as a hard disk. Backing up computers is especially important for enterprises because enterprises are at great risk of losing sensitive data due to security breaches, crashes, and network outages.
Even experienced MSPs have questions regarding archiving and backups: how are they identified, how do they differ, and which are more valuable to customers?
Since we previously examined the definition of a computer backup, we will continue archiving. As a provider of managed services, you have many responsibilities. If you want your computer to backup regularly, you are often responsible for full monitoring of client networks, archiving data, tracking IT resources and user activity, and managing cloud servers.

Full Backup:
A full backup is a complete copy of a data and provides the best protection. However, most companies periodically use full backups only because they take a lot of time and require enough storage space.
Incremental Backup:
Incremental backups only back up data that has changed since the previous backup, which makes them less time consuming than full backups.
Differential Backup:
Like incremental backups, reconstructive backups only back up changed data. In differential all data is placed since the last backup.
