Abstract
Systems and methods for replicating a device image to a storage such as the cloud. The cloud is seeded with a base image that corresponds to the device. Changes between the contents of the device and the base image are identified, uploaded to the cloud, and applied to the image. The changes are tracked continuously and the image in the cloud can thus be used to restore the device to any point in time. The cloud image can also be used in a cloud based virtual machine that provides a user of the device with access to the device's contents via the cloud based image.
Claims20
A method for replicating contents of a storage device associated with a client device to a target site, the method comprising:
- selecting a seed image associated with the storage device from a plurality of seed images stored in an image repository and storing the seed image at the target site, wherein contents of the seed image were not transmitted to the target site from the client device;
- determining changes between the contents of the storage device and the seed image by comparing the contents of the storage device with contents of the seed image stored at the target site;
- transmitting the changes to the target site;
- incorporating the changes into the seed image to generate an initial image of the storage device.
A method for replicating contents of a storage device of a client device to a cloud, the method comprising:
- comparing contents of the storage device with contents of a seed image stored in the cloud, wherein the seed image is not transmitted from the client device;
- uploading the contents of the storage device that are different from the content of the seed image to the cloud;
- incorporating the uploaded contents of the storage device into the seed image to generate an initial image of the storage device;
- and
- tracking changes at the client device and uploading the changes to the cloud;
- and
- incorporating the tracked changes into the initial image to generate an image of the storage device that corresponds to a different point in time than the initial image.
