Hello Maria,
I am not sure about Italy Legal regulations but I don't think all data is related to these rules.
And also archiving does not mean of deleting the data. When you archive, you can reach the data but not as fast as standart way.
You strategy is important when you are archiving your data.
Which data will you archive? Archiving objects?
How much data will you keep in DB?
I advise you to ask the issue to your customer represantative at SAP Italy.
Or you can open OSS message.
Regards,
Yuksel AKCINAR
