Full backup

A full backup is a method of backup where all files and folders are selected to perform a backup. It is used from initial or the first backup according to the prompt after which incremental and differential backups are done. Likewise doing incremental and differential backups are done, it is very common that we start again with a fresh full backup. Restoring then is very easy and fast because the entire list of files and folders are saved in the same backup set.

Incremental backup

It’s a backup in which all the changes that occur are after the last backup. Here the last backup can be a full backup of simple an incremental backup.

  • These are much faster backups
  • There is an efficient use of storage space here because files are not duplicated.

Restore here is much slower than the full backups and differential backups.
Restores are also a bit complicated with it.

Differential backup

Differential backup always comes in the middle Of incremental backup and differential backup.

If we set differential Backup that they are backup all night from Monday to Friday then as we know that the first backup that happens will be a full backup.

  • These are much faster backups then full backups
  • In this, the storage space is used efficiently because only the changes data is backup in them.

Mirror backup

As its name suggests, it’s called the backup where the backup of the source is stored in a space such that a mirror becomes an image of the original image. But here in mirror backups, whenever a file is deleted in a source, it is automatically deleted in its mirror backup as well.
