Abstract

The disclosed computer-implemented method for generating full backups of applications may include (1) storing, at a backup server that is remote from an application, an initial full backup of the application that indicates an initial version of each data block within the application, (2) after storing the full backup of the application, receiving, from the application, an incremental log file generated by the application that indicates at least one change made to a data block within the application after the initial full backup of the application was generated, and (3) creating, by applying the change made to the data block within the application to the initial full backup of the application, an updated full backup of the application that indicates the most current version of each data block within the application. Various other methods, systems, and computer-readable media are also disclosed.

Claims

1. A computer-implemented method for generating full backups of applications, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:

storing, at a backup server that is remote from an application, an initial full backup of the application that indicates an initial version of each data block within the application;

after storing the initial full backup of the application, receiving, from the application, an incremental log file generated by the application that indicates at least one change made to a corresponding data block within the application after the initial full backup of the application was generated; and

creating an updated full backup of the application that indicates the most current version of each data block within the application by;

replicating a computing environment in which the application is designed to run;

loading a copy of the initial full backup of the application into a portion of fast-access memory within the replicated computing environment; and

recreating the at least one change made to the corresponding data block within the copy of the initial full backup of the application by;

identifying, based on the incremental log file, input provided to the application that resulted in the at least one change being made to the corresponding data block within the application; and

providing, to the copy of the initial full backup of the application within the portion of fast-access memory within the replicated computing environment, the input that resulted in the at least one change being made to the corresponding data block within the application.

2. The method of claim 1, further comprising storing both the updated full backup of the application and the initial full backup of the application within the backup server.

3. The method of claim 2, further comprising:

receiving an additional incremental log file generated by the application that indicates an additional change made to the corresponding data block within the application after the updated full backup of the application was created;

creating a most-recently updated full backup of the application by recreating the additional change made to the corresponding data block within a copy of the updated full backup of the application; and

storing the most-recently updated full backup of the application in addition to the initial full backup of the application and the updated full backup of the application.

4. The method of claim 1, further comprising storing an indication of the at least one change made to the corresponding data block within the application.

5. The method of claim 4, further comprising:

receiving a request to obtain a version of the application as the application was when the initial full backup of the application was generated; and

in response to the request, using the stored indication of the at least one change made to the corresponding data block to return the updated full backup of the application to a state that represents the version of the application as the application was when the initial full backup of the application was generated.

6. The method of claim 1, further comprising:

receiving, from the application, an additional incremental log file generated by the application that indicates an additional change made to the corresponding data block within the application after the updated full backup of the application was created;

creating a most-recently updated full backup of the application by overwriting the updated full backup of the application based on the additional change made to the corresponding data block within the application; and

storing an indication of the additional change made to the corresponding data block within the application.

7. The method of claim 1, wherein replicating the computing environment in which the application is designed to run comprises:

determining that the backup server that stores the initial full backup of the application runs an operating system that is not compatible with an operating system that executes the application; and

sending, in response to determining that the operating system run by the backup server is not compatible with the operating system that executes the application, at least a portion of the updated full backup of the application to a proxy server that runs an operating system that is compatible with the operating system that executes the application.

8. The method of claim 1, wherein creating the updated full backup of the application comprises utilizing at least one application program interface to recreate the at least one change made to the corresponding data block within the application within the copy of the initial full backup of the application.

9. The method of claim 1, wherein the portion of fast-access memory within the replicated computing environment is:

contained within the backup server; and

distinct from a portion of memory that stores a filesystem of the backup server.

10. The method of claim 1, wherein the portion of fast-access memory comprises a cache.

11. A system for generating full backups of applications, the system comprising:

a storage module, stored in memory, that stores, at a backup server that is remote from an application, an initial full backup of the application that indicates an initial version of each data block within the application;

a reception module, stored in memory, that receives, from the application, after the initial full backup of the application is stored, an incremental log file generated by the application that indicates at least one change made to a corresponding data block within the application after the initial full backup of the application was generated;

a creation module, stored in memory, that creates an updated full backup of the application that indicates the most current version of each data block within the application by;

replicating a computing environment in which the application is designed to run;

loading a copy of the initial full backup of the application into a portion of fast-access memory within the replicated computing environment; and

recreating the at least one change made to the corresponding data block within the copy of the initial full backup of the application by;

identifying, based on the incremental log file, input provided to the application that resulted in the at least one change being made to the corresponding data block within the application; and

providing, to the copy of the initial full backup within the portion of fast-access memory within the replicated computing environment, the input that resulted in the at least one change being made to the corresponding data block within the application; and

at least one hardware processor configured to execute the storage module, the reception module, and the creation module.

12. The system of claim 11, wherein the storage module stores both the updated full backup of the application and the initial full backup of the application within the backup server.

13. The system of claim 12, wherein:

the reception module further receives an additional incremental log file generated by the application that indicates an additional change made to the corresponding data block within the application after the updated full backup of the application was created;
