Can I make Synthetic Full Backup or Reverse Incremental Backup?

[CleriC]

Tell me, plz, is it possible (and how) to configure Cobian Backup so that it does not recreate the full copy, but complements it? If I understand correctly, this is called a Synthetic Full Backup (pic).

From my experience with this program, if you configure, for example, Differential copying (3 copies), then it will first create a full one, then it will make Differential copies for 3 days, and then it will create a new full one again (and delete the old full one).

If we are talking about copying a very large amount of data (1 Tb and above), of which only a couple of gigabytes change, then I would not like to recreate this entire volume on a regular basis. But at the same time, having several intermediate copies (i.e. just a full backup of the mirror type will not work).

Reverse Incremental Backup (pic) also can fit, but how to configure it?

Just do NOT create new backups regularly. Play with the dynamic settings.
