The invention relates to computer networks and to a digital data protection thereon, in particular to a method for the distributed backup of a digital data block (B) in an computer network comprising a DHT distributed hash table and at least one node NO, wherein said NO nodes are connected to said network. The inventive method consists individing said block B into digital data r fragments F, in storing the fragment F in the NO, resource memories, in recording couples (block B, node NO) and (node NO, fragment F) in the DHT parts contained in at least two nodes and in a centralised server when no operation on the DHT or storage operation is carried out during said process.
