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.
