How Do I Set Incremental Backups?

What is an incremental backup/cloning and how do I enable it in Personal Backup?

Incremental backup means that after your initial backup, all subsequent backups will copy only new and modified files. This will save time by not copying files that have not changed since your last backup. The same idea applies to cloning.

Note: This feature is on by default. There is nothing the user needs to do to enable it.  It will also only work when the source and destination remain the same.
