Abstract

A system and method is disclosed for live virtual incremental restoring of data from a cloud storage. An example method includes, in response to detecting a data backup, collecting information by a hardware processor of a computing device for configuring a list of changed sectors (LCS) of a storage medium of the computing device as a result of the data backup. The method further includes virtually restoring at least a portion of electronic data saved in the storage medium of the computing device from the cloud storage, the selected electronic data being previously saved in the cloud storage. The method also includes rebooting the computing device and applying changes to the storage medium of the computing device based on the LCS during a subsequent data backup.

3. The method of claim 2, wherein the dedicated boot loader of the computing device is further configured to:

reboot the computing device by deactivating a default boot loader of the computing device;

establish a connection to the cloud storage;

set hooks to intercept input/output (I/O) requests into the dedicated boot loader and the default boot loader on the VVS; and

activate the default boot loader.

4. The method of claim 3, further comprising:

running an operating system (OS) of the computing device based on information stored on the VVS for checking applications and data associated with the computing device; and

5. The method of claim 3, further comprising:

running an operating system (OS) of the computing device based on information stored on the VVS for checking applications and data associated with the computing device; and

in response to a command to restore data, checking one or more restored sectors that are detected based on an indicia;

redirecting the one or more write requests to the storage medium of the computing device and marking corresponding sectors of the storage medium as restored; and

copying sectors from the dedicated storage and the cloud storage and marking the sectors as restored.

6. The method of claim 5, further comprising:

in response to detecting all sectors being marked as restored, disabling the dedicated boot loader and unloading the hooks.

7. The method of claim 6, further comprising restoring a plurality of sectors of the computing device based on a priority determined based at least upon a usage frequency of each sector.

8. The method of claim 2, further comprising:

in response to detecting that an activated working mode of the computing device disables the dedicated storage, directing all data requests to the storage medium of the computing device to the dedicated storage before rebooting the computing device, and disabling the dedicated storage by the dedicated boot loader.

9. A system for live virtual incremental restoring of data from a cloud storage, the system comprising:

an electronic memory; and

a hardware processor couple to the electronic memory and configured to;

in response to detecting a data backup, collect information for configuring a list of changed sectors (LCS) of the electronic memory of the computing device as a result of the data backup;

virtually restore at least a portion of electronic data saved in the electronic memory of the computing device from the cloud storage, the selected electronic data being previously saved in the cloud storage; and

reboot the computing device and apply changes to the electronic memory of the computing device based on the LCS during a subsequent data backup.

10. The system of claim 9, wherein the processor is further configured to create a virtual volume set (VVS) by a dedicated boot loader of the computing device in response to the data backup to:

detect one or more write requests to the electronic memory of the computing device occurred during two consecutive data backups;

store the one or more write requests in a dedicated storage associated with the VVS;

in response to determining that a requested sector corresponding to at least one read request is located in the dedicated storage, obtain information relating to data changes from the dedicated storage;

in response to determining that the requested sector is located in the LCS, obtain information relating to data changes from the cloud storage; and

in response to determining that the requested sector is not located in the LCS, obtain information relating to data changes from an original volume of the requested sector.
