How Many Types of Backup are There?
« on: August 26, 2021, 09:02:50 AM »
There are mainly three types of backup: full, differential, and incremental.

Full Backup
A full data backup support is the most complete type of backup where you clone all the selected data. This includes files, folders, SaaS applications, hard drives, and more. The highlight of a full backup is the minimal time it requires to restore data. However, since as everything is backed up in one go, it takes longer to backup compared to other types of backup.

The other common issue with running full backups is that it overloads storage space. That’s why most businesses tend to run a full backup and occasionally follow it up with differential or incremental backup. This reduces the burden on the storage space, increasing backup speed.

Differential Backup
A differential backup straddles the line between a full and an incremental backup. This type of backup involves backing up data that was created or changed since the last full backup. To put it simply, a full backup is done initially, and then subsequent backups are run to include all the changes made to the files and folders.

It lets you restore data faster than a full backup since it requires only two backup components: an initial full backup and the latest differential backup.

There are 4 type of backup

Incremental backup : This is a backup that copies only data that has changed since the last backup copy was produced.
Full backup : Full backups is all about as per name. In that each and every file or data copied.
Differential backup : A differential backup is a form of data backup that saves only the difference between the current backup and the previous complete backup.
Mirror backup : In mirror backup when user can select folders for backup then only selected folders was copied.
