Abstract
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 in dividing said block B into digital data r fragments F, in storing the fragment F in the NOF resource memories, in recording couples (block B, node NOF) and (node NOF, 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.
