receiving an authentication success message returned after the one or more target backup devices use the public key to check the signed character string, and determining that the character string obtained after checking is the same as the generated character string, or determining that the authentication obtained after checking is different from the generated character string, and then returning authentication failure;
determining that the one or more target backup devices pass the authentication according to the authentication success message; or
And determining that the authentication with the one or more target backup devices fails according to the authentication failure message.
4. The method of claim 1, wherein performing device authentication with the one or more target backup devices over the established connection comprises:
receiving a certificate sent by the one or more target backup devices, wherein the certificate carries a public key;
sending a character string generated after the certificate is verified to be successful to the one or more target backup devices;
receiving the one or more target backup devices signing the character string according to a private key corresponding to the public key to obtain a signed character string;
using the public key to verify the signed character string;
determining that the one or more target backup devices pass the authentication under the condition that the character string obtained after the signature verification is the same as the generated character string;
and determining that the one or more target backup devices are not authenticated under the condition that the character string obtained after the signature verification is different from the generated character string.
5. The method of claim 1, wherein backing up data to the one or more target backup devices comprises:
establishing a security transport layer protocol (TLS) channel with the one or more target backup devices, and backing up the data carrying the retrieval identifier to a backup database of the one or more target backup devices through the TLS channel; or
And encrypting the data in an encryption mode negotiated with the one or more target backup devices in advance, and sending the encrypted data to the one or more target backup devices.
6. The method of any of claims 1 to 5, wherein after backing up data into the one or more target backup devices, the method further comprises:
receiving data of the one or more target backup devices, wherein the data carries retrieval identifiers;
storing data of the one or more target backup devices in a backup database.
7. The method of claim 6, wherein after storing the data of the one or more target backup devices in a backup database, the method further comprises:
and searching the data of the one or more target backup devices from the backup database according to the retrieval identification.
8. A data backup processing apparatus, comprising:
the first receiving module is used for receiving a trigger instruction for starting a data backup function and initiating a searching device instruction for searching backup devices according to the trigger instruction;
a second receiving module, configured to receive a response message sent by one or more target backup devices, where the response message carries IP addresses of the one or more target backup devices;
the connection establishing module is used for establishing connection with the one or more target backup devices according to the IP address;
the authentication module is used for performing equipment authentication with the one or more target backup equipment through the established connection;
and the backup module is used for backing up the data to the one or more target backup devices after the authentication is passed.
9. A computer-readable storage medium, in which a computer program is stored, wherein the computer program is configured to carry out the method of any one of claims 1 to 7 when executed.
10. An electronic device comprising a memory and a processor, wherein the memory has stored therein a computer program, and wherein the processor is arranged to execute the computer program to perform the method of any of claims 1 to 7.
