A computer-implemented method may include identifying a request to restore an image to a target disk while a first operating system is running on the target disk and creating a file in a first file system of the first operating system. The method may also include mapping a position in the file to a location on the target disk to provide a map that associates the position in the file with the location on the target disk. The method may further include using the map to write at least a portion of the image to the target disk to provide a restored operating system on the target disk. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for restoring images

A cloning manager reads contents of a source file system as a stream of objects. The cloning manager identifies a destination file system into which to merge the source file system stream during the cloning operation. The cloning manager proceeds to merge objects of the source file system stream into the destination file system according to a specific merging strategy, replacing some or all corresponding objects in the destination file system with their counterpart objects from the source file system stream, or preserving corresponding objects in the destination by discarding their counterpart objects from the source, as desired.

Merging file systems during a disk clone operation

A cloning manager preserves in-place file system objects during a clone operation. The cloning manager determines boundaries of a file system to be created by the clone operation, and identifies at least one protected area within the boundaries, reserved for the file system. The cloning manager also identifies at least one in-place file system object within or overlapping the boundaries to be preserved during the clone operation. The cloning manager ensures that each object to be preserved is not located in a protected area, shifting the objects as necessary. The cloning manager creates the file system during the clone operation only in locations that do not contain objects to be preserved.

In-place preservation of file system objects during a disk clone operation

A cloning manager preserves in-place file system objects during a clone operation. The cloning manager determines boundaries on a target storage medium to contain a resultant file system to be created by the clone operation, and identifies at least one protected area within the boundaries to be overwritten by the clone operation. The cloning manager also identifies at least one in-place file system object at least partially within the boundaries not to be overwritten during the clone operation. The cloning manager ensures that each in-place file system object is not located in a protected area, shifting the objects as necessary. The cloning manager performs the clone operation, creating the resultant file system only in locations within the boundaries in which no in-place file system object is located.

A system and a method are disclosed for creating a new partition. The technique includes initially allocating initially available sectors in a designated new partition area of a source partition to the new partition and subsequently allocating additional sectors in the designated new partition area of the source partition to the new partition that have subsequently become available.
