Abstract

A computer-implemented method may comprise performing a disaster recovery restore process on a target computing device; accessing a backup server; and selecting a source backup from the backup server. The source backup may comprise one or more volumes, partitions, files and device drivers of a source computing device from which the source backup was created. The selected source backup may then be installed in an offline partition of the target computing device. One or more target device drivers may then be installed in the offline partition. To complete the disaster recovery restore process on the target computing device, the target computing device may then be rebooted. Both the backup of the source computing device and the active partition of the target device may comprise source computing device-dependent hardware device drivers. When carried out in a Windows® environment, Sysprep need not be used and the kernel need not be modified.

(iii) restoring the target computing device using the selected source backup and configuring the target computing device with the first network address and a second hostname that is different from the first hostname; and

(iv) restoring the target computing device using the selected source backup and configuring the target computing device with a second hostname that is different from the first hostname and a second network address that is different from the first network address; and

restoring the target computing device according to the selected disaster recovery option.

2. The computer-implemented method of claim 1, further comprising rebooting the target computing device to complete the disaster recovery restore process on the target computing device.

3. The computer-implemented method of claim 2, wherein rebooting comprises rebooting the target computing device a single time to complete the disaster recovery restore process.

4. The computer-implemented method of claim 1, wherein at least one of the plurality of disaster recovery options comprises configuring the restored target computer for automatic backup with the backup service.

5. The computer-implemented method of claim 1, wherein at least one of the plurality of disaster recovery options comprises configuring the restored target computing device for automated backup with the backup service at restore time.

6. The computer-implemented method of claim 1, wherein selecting disaster recovery option (i) allows the source backup to be changed according to changes to the restored target computing device.

7. The computer-implemented method of claim 1, wherein selecting disaster recovery options (ii), (iii) or (iv) preserves unchanged the source backup in the backup service.

8. The computer-implemented method of claim 1, wherein selecting one of a plurality of available disaster recovery options is performed at restore time.

9. The computer-implemented method of claim 1, further comprising presenting credentials to the backup service before selecting a source backup from the backup service.

10. The computer-implemented method of claim 1, wherein selecting a source backup from the backup service further comprises:

selecting at least one volume from the source backup; and

restoring the selected at least one volume of the target computing device according to the selected disaster recovery option.

11. The computer-implemented method of claim 1, wherein at least the target computing device comprises a version of Microsoft Windows®

7 or above.

12. The computer-implemented method of claim 1, wherein selecting one of a plurality of available disaster recovery options is performed based upon user input.

13. A non-transitory machine-readable medium having data stored thereon representing sequences of instructions which, when executed by a target computing device, cause the target computing device to:

access, over a computer network, a backup service;

select a source backup from the backup service, the source backup comprising at least one volume of a source computing device from which the source backup was created, the source computing device being associated with a first hostname and a first Internet Protocol (IP) address;

select one of a plurality of available disaster recovery options, the plurality of available disaster recovery options comprising at least two of;

(i) restore a target computing device using the selected source backup and configure the target computing device with the first hostname and the first IP address;

(ii) restore the target computing device using the selected source backup and configure the target computing device with the first hostname and a second IP address that is different from the first IP address;

(iii) restore the target computing device using the selected source backup and configure the target computing device with the first IP address and a second hostname that is different from the first hostname; and

(iv) restore the target computing device using the selected source backup and configure the target computing device with a second hostname that is different from the first hostname and a second IP address that is different from the first IP address; and

restore the target computing device according to the selected disaster recovery option.
