Abstract

Embodiments of the present disclosure relate to a method, device and computer readable medium for restoring files. The method described herein comprises: at a client, in response to receiving an instruction for restoring a set of files on a virtual machine from a backup server, obtaining a backup of a set of files from the backup server; transmitting information about the backup and a file downloading application to the virtual machine; causing the file downloading application to be executed on the virtual machine by transmitting an instruction for executing the file downloading application to the virtual machine, such that the virtual machine downloads the backup from the client based on the information about the backup.

Claims

1. A method of restoring files, comprising:

at a client,

in response to receiving from a backup server an instruction for restoring a set of files on a virtual machine, mounting, by the client, a backup server storage device of the backup server, wherein the backup server storage device comprises a backup of the set of files;

transmitting information about the backup and a file downloading application to the virtual machine, wherein the information about the backup comprises a target storage path of a storage on the virtual machine; and

causing the file downloading application to be executed on the virtual machine by transmitting an instruction for executing the file downloading application to the virtual machine, such that upon execution of the file downloading application the virtual machine downloads the backup from the client based on the information about the backup.

2. The method according to claim 1, wherein the information about the backup further comprises:

an identification of the backup.

3. The method according to claim 2, further comprising:

storing, at the client, the identification of the backup in association with an access path of the backup on the client, wherein the access path is to the backup of the set of files stored on the backup server storage device.

4. The method according to claim 3, further comprising:

receiving, from the virtual machine, a request for downloading the backup, the request including the identification of the backup;

determining the access path of the backup on the client based on the identification in the request;

reading the backup via the access path; and

transmitting, to the virtual machine, a download response including the backup.

5. The method according to claim 1, further comprising:

in response to completion of the downloading, causing the virtual machine to remove the information about the backup and the file downloading application.

6. An electronic device, comprising:

at least one processor; and

at least one memory including computer program instructions, the at least one memory and the computer program instructions configured, with the at least one processor, to cause the device to perform a method, the method comprising;

in response to receiving from a backup server an instruction for restoring a set of files on a virtual machine, mounting, by the client, a backup server storage device of the backup server, wherein the backup server storage device comprises a backup of the set of files;

transmitting information about the backup and a file downloading application to the virtual machine, wherein the information about the backup comprises a target storage path of a storage on the virtual machine; and

causing the file downloading application to be executed on the virtual machine by transmitting an instruction for executing the file downloading application to the virtual machine, such that upon execution of the file downloading application the virtual machine downloads the backup from the client based on the information about the backup.

7. The electronic device according to claim 6, wherein the information about the backup further comprises:

an identification of the backup.

8. The electronic device according to claim 7, wherein the method further comprises:

storing, at the client, the identification of the backup in association with an access path of the backup on the client, wherein the access path is to the backup of the set of files stored on the backup server storage device.

9. The electronic device according to claim 8, wherein the method further comprises:

receiving, from the virtual machine, a request for downloading the backup, the request including the identification of the backup;

determining the access path of the backup on the electronic device based on the identification in the request;

reading the backup via the access path; and

transmitting, to the virtual machine, a download response including the backup.

10. The electronic device according to claim 6, wherein the method further comprises:

in response to completion of the downloading, causing the virtual machine to remove the information about the backup and the file downloading application.

11. A non-transitory computer readable medium comprising machine executable instructions, the machine executable instructions, when executed by a device, cause the device to perform a method, the method comprising:

in response to receiving from a backup server an instruction for restoring a set of files on a virtual machine, mounting, by the client, a backup server storage device of the backup server, wherein the backup server storage device comprises a backup of the set of files;

transmitting information about the backup and a file downloading application to the virtual machine, wherein the information about the backup comprises a target storage path of a storage on the virtual machine; and

causing the file downloading application to be executed on the virtual machine by transmitting an instruction for executing the file downloading application to the virtual machine, such that upon execution of the file downloading application the virtual machine downloads the backup from the client based on the information about the backup.

12. The non-transitory computer readable medium according to claim 11, wherein the information about the backup further comprises:

an identification of the backup, and

a storage path of the backup on the virtual machine.

13. The non-transitory computer readable medium according to claim 12, the method further comprising:

storing, at the client, the identification of the backup in association with an access path of the backup on the client, wherein the access path is to the backup of the set of files stored on the backup server storage device.

14. The non-transitory computer readable medium according to claim 13, the method further comprising

receiving, from the virtual machine, a request for downloading the backup, the request including the identification of the backup;

determining the access path of the backup on the client based on the identification in the request;

reading the backup via the access path; and

transmitting, to the virtual machine, a download response including the backup.

15. The non-transitory computer readable medium according to claim 11, the method further comprising:

in response to completion of the downloading, causing the virtual machine to remove the information about the backup and the file downloading application.
