1. A method comprising:
- identifying, by one or more computer processors, 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;
querying a relational data structure to determine when a full backup of the virtual machine has been generated and stored;
responsive to generation of the full backup of the virtual machine, creating, by one or more computer processors, an incremental backup of the virtual machine;
storing, in one or more storage devices, by one or more computer processors, the incremental backup of the virtual machine;
confirming, by one or more computer processors, 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, by querying the relational data structure;
creating, by one or more computer processors, a backup of the log data associated with the application;
storing in one or more storage devices, by one or more computer processors, the backup of the log data; and
relating in the relational data structure, by one or more computer processors, 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.
