How to create a differential backup

This article shows how to create a differential backup of the given sources to a specified destination using Backup4all. The current method can be extended to other sources and destinations supported by Backup4all.

Backup execution examples

We will perform several backup executions to see what we get in destination.

  1. As we have sources from C and D drive, after the first backup execution, we get in destination a zip file for each source drive: 1_C.zip and 1_D.zip

  2. For the second backup execution we will add a new folder called "03" in backup sources on D: drive.

  3. After the 2nd backup execution we get in destination: 2\_D.zip which is the second backup version, containing only folder "03".

  4. For the third backup execution we will change an existing source file on C: drive.
