What’s the Difference between Backup and Copy

Why backup, not copy?

You must have been asked to back up the data to prevent unexpected loss. And you’ve probably been told to choose the right backup software to do so. For example, to perform virtual machine backup. Why not just copy everything? What’s the difference between backup and copy?

In fact, the key difference between backup and copy is precisely that you cannot really copy everything, but backups can. In terms of scope, copy is a subset of backup.

What is backup

A backup contains not only all the data, but also the system registry files, application configuration files, and all other hidden, invisible, and protected files. These cannot be copied manually.

Therefore, backups can keep the history record for tracking, and tend to involve compression, encapsulation, encryption, etc.

The golden 3-2-1 backup rule:

To summarize, Backup = Copy + Management. The management includes plans for backups, automated operation of tape drives, preservation of history, and logging. These backup options are not available with manual copying.

What backup options are available

Backup has many more freely selectable backup options than copy. They are usually provided by backup software to meet different backup needs and to increase efficiency and security, reduce costs. This is crucial for businesses.

Here I summarized some common available backup options according to different categorization criteria.

According to the amount of backup content

• Full backup: A complete backup that contains all of data you want to back up.
• Differential backup: Back up only the data that has changed since the last full backup. Restore requires the full backup which was the differential base, and the last differential backup.
• Incremental backup: Back up only the data that has changed from the last backup. Restore requires the full backup which was the incremental base, and all incremental backups.

According to the storage location of the backup files

• Local backup: Store the backup files in the local path.
• Remote backup: Store the backup files on the remote server, for example, a network share, or cloud.

According to the backup frequency

• Immediate backup: Perform backup once by manual operation.
• Regular backup: Create a backup schedule to perform backups periodically.

What’s the difference between backup and copy

So, what is the difference between backup and copy paste? Read this far, you must have already got an idea. In general, it can be summarized into 2 points.

• Content: A copy actually cannot really copy everything, but backups can.
• Options: There are many freely selectable backup options to meet different needs than direct copy.
