If I remember right, those ASHAMPOO products, which versioning is based on the year (“2021” etc.) were always(!) given away for free – at last starting with the following year?! (And often even much earlier…)
And those version are always limited, compared to their “main” versions, e.g. ASHAMPOO xxx (Backup…) 14, 15, 16, 17…
BUT this 2021 version is a good choice, if one does not need the cloud-backup ability, offered by Backup 14/15/16/17
Anyhow : I would prefer Version 16, which is still available “for free” (find my ASHAMPOO Backup deal at mydealz.de )
