1. A computer program product comprising:
- one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising;
program instructions to identify an application executing in a guest operating system in a virtual machine and log data associated with the application, wherein the log data represents changes to data of SQL database transaction logs that have occurred since a point in time;
program instructions to query a relational data structure to determine when a full backup of the virtual machine has been generated and stored;
program instructions, responsive to generation of the full backup of the virtual machine, to create an incremental backup of the virtual machine;
program instructions to store the incremental backup of the virtual machine;
program instructions to confirm that the full and incremental backups of the virtual machine have been stored in the one or more storage devices, and that the full and incremental backups of the virtual machine are in a data format that is compatible with a data format used to back up the log data, via the relational data structure;
program instructions to create a backup of the log data;
program instructions to store the backup of the log data; and
program instructions to relate in the relational data structure the full and incremental backups of the virtual machine and the backup of the log data.

Abstract
Embodiments of the present invention provide efficient and cost-effective systems and methods for backing up and recovering a virtual machine and application data therein. Embodiments of the present invention can be used to satisfy near-zero RPOs by providing more recovery points for backups in virtual machine environments, while also providing increased granularity for recovery (i.e., single virtual disk, single file, etc.) and maintaining central management capabilities and back up efficiencies offered by virtual machine-level backups.

8. A computer system comprising:
-
one or more computer processors; one or more computer readable storage media; program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising; program instructions to identify an application executing in a guest operating system in a virtual machine and log data associated with the application, wherein the log data represents changes to data of SQL database transaction logs that have occurred since a point in time; program instructions to query a relational data structure to determine when a full backup of the virtual machine has been generated and stored; program instructions, responsive to generation of the full backup of the virtual machine, to create an incremental backup of the virtual machine; program instructions to store the incremental backup of the virtual machine; program instructions to confirm that the full and incremental backups of the virtual machine have been stored in the one or more storage devices and that the full and incremental backups of the virtual machine are in a data format that is compatible with a data format used to back up the log data, via the relational data structure; program instructions to create a backup of the log data; program instructions to store the backup of the log data; and program instructions to relate in the relational data structure the full and incremental backups of the virtual machine and the backup of the log data. - View Dependent Claims (9, 10, 11, 12, 13)
