The 3-2-1 rule recommended three copies of data on two different media, with one copy off-site. Initially proposed by Peter Krogh, this rule needs to adapt to today's evolving risks. In a digital landscape that is constantly growing and interacting, more advanced backup strategies are emerging to meet these needs. Veeam, for example, promotes the 3-2-1-1-0 rule, which meets the objective of ensuring data recovery by diversifying storage copies. By integrating these principles into their practices, companies can guarantee the security and availability of their data in a dynamic digital environment.<\/p>\n\n\n\n
