Method of merging a clone file system with an original file system
First Claim
Patent Images
1. A computerized method, comprising:
- saving metadata about an original file system;
creating a clone file system of the original file system; and
thenmaking a first modification to the original file system;
making a second modification to the clone file system, the first modification different than the second modification; and
thenidentifying the first modification based on the metadata; and
merging the first modification into the clone file system such that the clone file system has, after the merging, both the first and second modification;
refraining from merging the second modification into the original file system until at least one boot of a computer system from the clone file system.

Abstract
Metadata about an original file system is saved at the time of creation of a clone file system of the original file system. The metadata is used at a later time to detect changes to the original file system. These changes are then applied to the clone file system which has its own changes different from the changes of the original file system. Changes made to the clone file system are merged into the original file system after at least one boot of a computer system from the clone file system.

7. A computer-readable storage medium storing a program that, when executed by a processor causes the processor to:
-
save metadata about an original file system; create, contemporaneously with saving the metadata, a clone file system of the original file system; and at a later time identify a first modification to the original file system based on the metadata; and merge the first modification into the clone file system such that the clone file system has, after the merging, the first modification and a second modification different than the first modification; prevent merging the second modification into the original file system until at least one boot of a computer system from the clone file system. - View Dependent Claims (8, 9, 10, 11, 12)
