Abstract

Embodiments of the systems and methods expose a form of backup data, referred to as snapshot data, to an online server. The snapshot data is copy of the directory system at a time in the past. The snapshot data, in embodiments, is exposed as an LDAP server database, which can be manipulated by one or more tools. Thus, the snapshot data is available to online servers to view, to compare, to restore, or to accomplish other actions on the data within the snapshot without server downtime.

Claims

1. A method executable in a computer system for manipulating snapshot data on an online server, the method comprising:

receiving a request for snapshot data;

determining a type of action requested to be performed on the snapshot data;

if the type of action is to view the snapshot data, viewing the snapshot data;

if the type of action is to compare the snapshot data, comparing the snapshot data; and

if the type of action is to restore the snapshot data, restoring the snapshot data.

2. The method as defined in claim 1, wherein viewing the snapshot data comprises:

exposing the snapshot data;

receiving a query to view the exposed snapshot data; and

providing a view of the snapshot data.

3. The method as defined in claim 2, further comprising:

determining if the requested snapshot data is located at a domain controller;

connecting to the domain controller to retrieve the snapshot data; and

authenticating a user to connect to the domain controller.

4. The method as defined in claim 2, wherein the snapshot data is exposed as an LDAP server.

5. The method as defined in claim 1, wherein comparing the snapshot data comprises:

exposing the snapshot data;

receiving a query to compare the exposed snapshot data; and

comparing the snapshot data.

6. The method as defined in claim 5, wherein two or more snapshots are compared.

7. The method as defined in claim 1, wherein restoring the snapshot data comprises:

exposing the snapshot data;

receiving a query to restore the exposed snapshot data; and

recreating the snapshot data.

8. The method as defined in claim 1, wherein restoring the snapshot data comprises:

exposing the snapshot data;

receiving a query to restore the exposed snapshot data;

reanimating tombstoned data; and

repopulating data sourcing from the snapshot data.

9. The method as defined in claim 8, further comprising:

determining if an object in the snapshot data is tombstoned;

if the object is tombstoned, reanimating the object and repopulating unpreserved attributes to the object based on snapshot data; and

if the object is not tombstoned, restoring object from the snapshot data.

10. The method as defined in claim 1, wherein the snapshot data comprises two or more snapshots.

11. The method as defined in claim 1, wherein the snapshot data comprises a portion of a snapshot.

12. A computer storage medium having computer-executable components stored thereon, the computer executable components executable in a computer system for manipulating snapshot data, the components comprising:

a user interface, the user interface receiving selections for snapshot data from a user and displaying snapshot data to the user;

a snapshot browser in communication with the user interface, the snapshot browser exposing snapshot data; and

a query processor in communication with the user interface and the snapshot browser, the query processor receiving a request from the user interface to manipulate snapshot data, the query processor, in response to the received request, manipulating snapshot data exposed by the snapshot browser.

13. The components as defined in claim 12, further comprising:

a snapshot manager in communication with the user interface, the snapshot manager providing discovery of one or more snapshots to the user, wherein the snapshot manager enumerates a set of snapshots from a domain controller and retrieves snapshot location information for each of the snapshots; and

a snapshot datastore in communication with the snapshot manager, the snapshot datastore storing snapshot data, wherein the snapshot location information identifies the location of the snapshot data.

14. The method as defined in claim 12, wherein the snapshot browser exposes the snapshot data as a database.

15. The method as defined in claim 14, wherein the snapshot data is exposed as a LDAP server.

16. A computer storage medium having computer-executable instructions stored thereon, the computer executable instructions comprising a method executable in a computer system for manipulating snapshot data, the method comprising:

providing discovery of one or more snapshots;

mounting one or more snapshots;

exposing one or more snapshots as an LDAP server;

receiving one or more action requests to manipulate the exposed snapshot data;

determining a type of action requested;

in response to the action request, manipulating the exposed snapshot data; and

providing the manipulated snapshot data.

17. The method as defined in claim 16, wherein two or more snapshots are exposed, wherein the type of action is determined to be a comparison, and wherein manipulating the exposed snapshot data comprises:

comparing a first snapshot with a second snapshot; and

generating a comparison of the first snapshot with the second snapshot.

18. The method as defined in claim 16, wherein the type of action is determined to be a view of the data, and wherein manipulating the exposed snapshot data comprises providing a view of the snapshot data as a database.

19. The method as defined in claim 16, wherein the type of action is determined to be a restoration of the data, and wherein manipulating the exposed snapshot data comprises:

determining if the exposed snapshot data was tombstoned;

if the exposed snapshot data was tombstoned, reanimating the tombstoned snapshot data; and

if the exposed snapshot data was not tombstoned, recreating the snapshot data in a directory system.

20. The method as defined in claim 16, wherein the providing discovery of one or more snapshots comprises:

connecting to a domain controller which stores a set of snapshots;

enumerating the set of snapshots; and

retrieving snapshot location information for each of the snapshots.
