Abstract

A method of storing encrypted data objects [figs. 7, 8] at a server, comprises; generating a data object 8 comprising chunks at a client computer 2; encrypting a first portion of chunks with a clientâ40 s private key 28; and sending the first portioof chunks and a second portion of chunks (not encrypted using the private key) to the server 4 to store in storage 6. Alternatively, the first or second portion of chunks may not be sent to the server if they are already stored at the server, to reduce the storage of duplicated or redundant data. The data objects may be sent to the server as back-up copies. The second portion of chunks may be encrypted using a key 30 shared between more than one client. On wishing the data object to be restored, the second portion of chunks is only transmitted to the client if the client can decrypt an encrypted identifier (encrypted using the private key), and transmit the correct decrypted identifier to the server.
