identifying one or more of the data items that have changed since a previous version was created; and

creating the version of the application data from the one or more of the data items.

8. The method of claim 6 , wherein preserving the configuration of the application at the first time comprises:

storing the version of application data and the application configuration in the secondary storage repository.

9. The method of claim 6 , wherein the application configuration includes parameters of the application to replicate processing results of the application corresponding to the first time.

10. The method of claim 6 , further comprising:

performing data integrity checks on the version of the application data.

11. A non-transitory machine-readable medium comprising instructions which, when read by a machine, cause the machine to perform operations in a method of application reification, the method comprising:

preserving a version of application data at a first time, the version of application data including a copy of a state of an application at the first time, the application executing on a host system separate from the application reification system;

preserving an application configuration of the application at the first time, the application configuration including information associated with the execution of the application at the first time;

at a second time subsequent to the first time, receiving, from the host system, a request to reify the application at the state corresponding to the first time in a container on the host system; and

in response to the request:

creating a container template, the container template including information associated with instantiating the container executing the application at the state corresponding to the first time, the container template including the application configuration of the application at the first time and a pointer to the version of the application data stored in a secondary storage repository, and

instantiating, based on the created container template, the container executing the application at the state corresponding to the first time;

copying the instantiated container on the application reification system; and

providing the container template to the host system for reifying the application at the state corresponding to the first time in the container by using the application data stored in the second storage repository.

12. The medium of claim 11 , wherein the application data comprises a database of data items stored in a primary storage repository and wherein preserving the version of the application data at a first time comprises:

identifying one or more of the data items that have changed since a previous version was created; and
