Abstract

Claims (31)

1. A method comprising: by one or more computing devices,

installing an application on at least a portion of a physical disk system associated with a first platform;

virtualizing the portion of the physical disk system into a virtual disk system, comprising:

storing data of the portion of the physical disk system in a database associated with the virtual disk system, wherein the database comprises one or more tables representing a hierarchical file system, one or more attributes, and one or more blocks of file content;

normalizing the one or more attributes, wherein normalizing the one or more attributes comprises normalizing at least one of a path, name, value, date and time of the data;

generating a platform neutral hierarchical file system based in part on the normalized one or more attributes;

providing an interface for user access to the data based, at least in part, on the one or more normalized attributes; and

providing a plurality of sets of drivers associated with a plurality of platforms, wherein each set of drivers supports, for an associated one of the platforms, native operations with respect to the portion of the physical disk system;

receiving user input to mount the virtual disk system on a second platform, the user input comprising authentication information;

determining, based at least in part on the authentication information and one or more of a network location of the user, a current time, or a number of accesses to the virtual disk system, whether to mount the virtual disk system on a second platform;

in response to a positive determination, mounting the virtual disk system on the second platform; and

executing the application on the second platform, wherein all operations associated with executing the application are contained within the virtual disk system mounted on the second platform, wherein executing the application on the second platform does not require any modification to the virtual disk system or to the data stored in the database of the virtual disk system.

2. The method of claim 1 , wherein executing the application on the second platform uses the set of drivers provided in the virtual disk system corresponding to the second platform.

3. The method of claim 1 , wherein executing the application on the second platform does not require any additional support outside of the virtual disk system from the second platform.

4. The method of claim 1 , wherein the data stored in the database of the virtual disk system comprise content of one or more files in the portion of the physical disk system of the first platform and one or more attributes describing a structure of the portion of the physical disk system of the first platform.

5. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to:

install an application on at least a portion of a physical disk system associated with a first platform;

virtualize the portion of the physical disk system into a virtual disk system, comprising:

storing data of the portion of the physical disk system in a database associated with the virtual disk system, wherein the database comprises one or more tables representing a hierarchical file system, one or more attributes, and one or more blocks of file content;

normalizing the one or more attributes, wherein normalizing the one or more attributes comprises normalizing at least one of a path, name, value, date and time of the data;

generating a platform neutral hierarchical file system based in part on the normalized one or more attributes;

providing an interface for user access to the data based, at least in part, on the one or more normalized attributes; and

providing a plurality of sets of drivers associated with a plurality of platforms, wherein each set of drivers supports, for an associated one of the platforms, native operations with respect to the portion of the physical disk system;

receive user input to mount the virtual disk system on a second platform, the user input comprising authentication information;

determine, based at least in part on the authentication information and one or more of a network location of the user, a current time, or a number of accesses to the virtual disk system, whether to mount the virtual disk system on a second platform;

in response to a positive determination, mount the virtual disk system on the second platform; and

execute the application on the second platform, wherein all operations associated with executing the application are contained within the virtual disk system mounted on the second platform, wherein the execution of the application on the second platform does not require any modification to the virtual disk system or to the data stored in the database of the virtual disk system.

6. The system of claim 5 , wherein executing the application on the second platform does not require any additional support outside of the virtual disk system from the second platform.

7. The system of claim 5 , wherein the data stored in the database associated with the virtual disk system comprise content of one or more files in the portion of the physical disk system of the first platform and one or more attributes describing a structure of the portion of the physical disk system of the first platform.
